HD74ALVCH162373
16-bit Transparent D-type Latches with 3-state Outputs
ADE-205-179 (Z)
Preliminary
1st. Edition
December 1996
Description
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. When LE is taken low, the Q outputs
are latched at the levels set up at the D inputs. Active bus hold circuitry is provided to hold unused or
floating data inputs at a valid logic level. All outputs, which are designed to sink up to 12 mA, include 26
resistors to reduce overshoot and undershoot.

undershoot > 2.0 V (@V
CC

High output current ±12 mA (@V
CC

Bus hold on data inputs eliminates the need for external pullup / pulldown resistors
All outputs have equivalent 26
series resistors, so no external resistors are required.
