The HD74ALVCH162373 is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

It can be used as two 8-bit latches or one 16-bit latch.

When the latch enable (LE) input is high, the Q outputs follow the data (D) inputs.

VCC = 2.3 V to 3.6 V.
Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C).
Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C).
High output current ±12 mA (@VCC = 3.0 V).
Bus hold on data inputs eliminates the need for external pullup / pulldown resistors.
All outputs have equivalent 26 Ω series resistors, so no external resistors are required. HD74ALVCH162373 Function Table Inputs OE L L L H LE H H L X D H L X X H L Q0.
