20-bit buffer/line driver, non-inverting, with 30W termination resistors (3-State)
74ABT162827A 74ABTH162827A
FEATURES
* Multiple VCC and GND pins minimize switching noise * Live insertion/extraction permitted * 3-State output buffers * Power-up 3-State * 74ABTH162827A incorporates bus-hold data inputs which
eliminate the need for external pull-up resistors to hold unused inputs
DESCRIPTION
The 74ABT162827A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. The 74ABT162827A 20-bit buffers provide high performance bus interface buffering for wide data/address paths or buses carrying parity. They have NOR Output Enables (nOE1, nOE2) for maximum control flexibility. The 74ABT162827A is designed with 30W series resistance in both the pull-up and pull-down output structures. This design reduces line noise in applications such as memory address drivers, clock drivers and bus receivers/transmitters. Two options are available, 74ABT162827A which does not have the bus-hold feature and 74ABTH162827A which incorporates the bus-hold feature.
* Output capability: +64mA/-32mA * Latch-up protection exceeds 500mA per Jedec Std 17 * ESD protection exceeds 2000 V per MIL STD 883 Method 3015
and 200 V per Machine Model

NOTES: 1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150C. 3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 1998 Feb 27 4

NOTES: 1. Not more than one output should be tested at a time, and the duration of the test should not exceed one second. 2. This is the increase in supply current for each input at 3.4V. 3. This parameter is valid for any VCC between 0V and 2.1V with a transition time of up to 10msec. From VCC = 2.1V to VCC = 5V 10% a transition time of up to 100sec is permitted. 4. Unused pins at VCC or GND. 5. This is the bus hold overdrive current required to force the input to the opposite logic state. 1998 Feb 27 5
