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

Ω resistors to reduce overshoot and undershoot.

Features

•

V_CC= 2.3 V to 3.6 V

Typical V_OLground bounce < 0.8 V (@V_CC= 3.3 V, Ta = 25°C)

Typical V_OHundershoot > 2.0 V (@V_CC= 3.3 V, Ta = 25°C)

High output current ±12 mA (@V_CC= 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.
