MC74HCT374A

Octal 3−State Noninverting

D Flip−Flop with

LSTTL−Compatible Inputs

High−Performance Silicon−Gate CMOS

The MC74HCT374A may be used as a level converter for

interfacing TTL or NMOS outputs to High−Speed CMOS inputs.

The HCT374A is identical in pinout to the LS374.

Data meeting the setup and hold time is clocked to the outputs with

the rising edge of Clock. The Output Enable does not affect the state of

the flip−flops, but when Output Enable is high, the outputs are forced

to the high−impedance state. Thus, data may be stored even when the

outputs are not enabled.

The HCT374A is identical in function to the HCT574A, which has

the input pins on the opposite side of the package from the output pins.

This device is similar in function to the HCT534A, which has

inverting outputs.

Features

— Improved Propagation Delays

— 50% Lower Quiescent Power

— Improved Input Noise and Latchup Immunity
