TECHNICAL DATA

Dual 2-Bit Transparent Latch

High-Performance Silicon-Gate CMOS

IN74HC75A

The IN74HC75A is identical in pinout to the LS/ALS75. The device

inputs are compatible with standard CMOS outputs; with pullup resistors,

they are compatible with LS/ALSTTL outputs.

This device consists of two independent 2-bit transparent latches and

can be used as temporary storage for binary information between

processing units and input/output or indicator units. Each latch stores the

input data while Latch Enable is at a logic low. The outputs follow the

data inputs when Latch Enable is at a logic high.

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 2.0 to 6.0 V

• Low Input Current: 1.0 µA

• High Noise Immunity Characteristic of CMOS Devices
