DESCRIPTION
The 74LVT162373 is a high-performance BiCMOS product designed for VCC operation at 3.3 V. This device is a 16-bit transparent D-type latch with non-inverting 3-State bus compatible outputs. The device can be used as two 8-bit latches or one 16-bit latch. When Latch Enable (LE) input is High, the Q outputs follow the data (D) inputs. When Latch Enable is taken Low, the Q outputs are latched at the levels of the D inputs one setup time prior to the High-to-Low transition. The 74LVT162373 is designed with 30 series resistance in both the High and Low states of the output. This design reduces the noise in applications such as memory address drivers, clock drivers, and bus receivers/transmitters.

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 negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.

NOTES: 1. All typical values are at VCC = 3.3V and Tamb = 25C. 2. This is the increase in supply current for each input at the specified voltage level other than VCC or GND. 3. This parameter is valid for any VCC between 0V and 1.2V with a transition time of up to 10msec. From VCC = 1.2V to VCC = 3.3V 0.3V a transition time of 100sec is permitted. This parameter is valid for Tamb = 25C only. 4. Unused pins at VCC or GND. 5. For valid test results, data must not be loaded into the flip-flops (or latches) after applying power. 6. ICCZ is measured with outputs pulled to VCC or GND. 7. This is the bus hold overdrive current required to force the input to the opposite logic state.
