1. general description the 74hc373-q100; 74hct373-q100 is a high -speed si-gate cmos device and is pin compatible with low- power schottky ttl. it is specif ied in compliance with jedec standard no. 7a. the 74hc373-q100; 74hct373-q100 is an octal d-type transparent latch featuring separate d-type inputs for each latch and 3-state outputs for bus-oriented applications. a latch enable (le) input and an output enable (oe ) input are common to all latches. the 74hc373-q100; 74hct373-q100 consists of eight d-type transparent latches with 3-state true outputs. when le is high, data at the dn inputs enters the latches. in this condition the latches are transparent, i.e. a latch output changes state each time its corresponding d input changes. when le is low, the latches store the info rmation that was present at the d inputs a set-up time preceding the high -to-low transition of le. when oe is low, the contents of the 8 latches are available at the outputs. when oe is high, the outputs go to the high- impedance off-state. operation of the oe input does not affect the state of the latches. the 74hc373-q100; 74hct373-q100 is functionally identical to: ? 74hc573-q100; 74hct573-q100: but different pin arrangement this product has been qualified to the automotive electronics council (aec) standard q100 (grade 1) and is suitable for use in automotive applications. 2. features and benefits ? automotive product qualif ication in accordance with aec-q100 (grade 1) ? specified from ? 40 ? c to +85 ? c and from ? 40 ? c to +125 ? c ? input levels: ? for 74hc373-q100: cmos level ? for 74hct373-q100: ttl level ? 3-state non-inverting outputs for bus-oriented applications ? common 3-state output enable input ? functionally identical to the 74hc573-q100; 74hct573-q100 ? esd protection: ? mil-std-883, method 3015 exceeds 2000 v ? hbm jesd22-a114f exceeds 2000 v ? mm jesd22-a115-a exceeds 200 v (c = 200 pf, r = 0 ? ) ? multiple package options 74hc373-q100; 74hct373-q100 octal d-type transparent latch; 3-state rev. 1 ? 10 august 2012 product data sheet

[2] the term ?short data sheet? is explained in section ?definitions?. [3] the product status of device(s) described in this document may have changed since this document was published and may differ in case of multiple device s. the latest product status information is available on the internet at url http://www.nxp.com . 15.2 definitions draft ? the document is a draft versi on only. the content is still under internal review and subject to formal approval, which may result in modifications or additions. nxp semiconductors does not give any representations or warranties as to the accuracy or completeness of information included herein and shall hav e no liability for the consequences of use of such information. short data sheet ? a short data sheet is an extract from a full data sheet with the same product type number(s) and title. a short data sheet is intended for quick reference only and should not be relied upon to contain detailed and full information. for detailed and full information see the relevant full data sheet, which is available on request vi a the local nxp semiconductors sales office. in case of any inconsistency or conflict with the short data sheet, the full data sheet shall prevail. product specification ? the information and data provided in a product data sheet shall define the specification of the product as agreed between nxp semiconductors and its customer , unless nxp semiconductors and customer have explicitly agreed otherwis e in writing. in no event however, shall an agreement be valid in which the nxp semiconductors product is deemed to offer functions and qualities beyond those described in the product data sheet. 15.3 disclaimers limited warranty and liability ? information in this document is believed to be accurate and reliable. however, nxp semiconductors does not give any representations or warranties, expressed or implied, as to the accuracy or completeness of such information and shall have no liability for the consequences of use of such info rmation. nxp semiconductors takes no responsibility for the content in this document if provided by an information source outside of nxp semiconductors. in no event shall nxp semiconductors be liable for any indirect, incidental, punitive, special or consequential damages (including - without limitation - lost profits, lost savings, business interruption, costs related to the removal or replacement of any products or rework charges) whether or not such damages are based on tort (including negligence), warranty, breach of contract or any other legal theory. notwithstanding any damages that customer might incur for any reason whatsoever, nxp semiconductors? aggregate and cumulative liability towards customer for the products described herein shall be limited in accordance with the terms and conditions of commercial sale of nxp semiconductors. right to make changes ? nxp semiconductors reserves the right to make changes to information published in this document, including without limitation specifications and product descriptions, at any time and without notice. this document supersedes and replaces all information supplied prior to the publication hereof. suitability for use in automotive applications ? this nxp semiconductors product has been qualified for use in automotive applications. unless otherwise agreed in writing, the product is not designed, authorized or warranted to be suitable for use in life support, life-critical or safety-critical systems or equipment, nor in applications where failure or malfunction of an nxp semiconductors product can reasonably be expected to result in personal injury, death or severe property or environmental damage. nxp semiconductors and its suppliers accept no liability for inclusion and/or use of nxp semiconducto rs products in such equipment or applications and therefore such inclusion and/or use is at the customer's own risk. applications ? applications that are described herein for any of these products are for illustrative purpos es only. nxp semiconductors makes no representation or warranty that such applications will be suitable for the specified use without further testing or modification. customers are responsible for the design and operation of their applications and products using nxp semiconductors products, and nxp semiconductors accepts no liability for any assistance with applications or customer product design. it is customer?s sole responsibility to determine whether the nxp semiconductors product is suitable and fit for the customer?s applications and products planned, as well as fo r the planned application and use of customer?s third party customer(s). customers should provide appropriate design and operating safeguards to minimize the risks associated with their applications and products. nxp semiconductors does not accept any liability related to any default, damage, costs or problem which is based on any weakness or default in the customer?s applications or products, or the application or use by customer?s third party customer(s). customer is responsible for doing all necessary testing for the customer?s applic ations and products using nxp semiconductors products in order to av oid a default of the applications and the products or of the application or use by customer?s third party customer(s). nxp does not accept any liability in this respect. limiting values ? stress above one or more limiting values (as defined in the absolute maximum ratings system of iec 60134) will cause permanent damage to the device. limiting values are stress ratings only and (proper) operation of the device at these or any other conditions above those given in the recommended operating conditions section (if present) or the characteristics sections of this document is not warranted. constant or repeated exposure to limiting values will permanently and irreversibly affect the quality and reliability of the device. terms and conditions of commercial sale ?
