MM74HC273

Octal D-Type Flip-Flops with Clear

Each output can drive 10 low power Schottky TTL equiva-

lent loads. The MM74HC273 is functionally as well as pin

compatible to the 74LS273. All inputs are protected from

damage due to static discharge by diodes to V_CCand

General Description

The MM74HC273 edge triggered flip-flops utilize advanced

silicon-gate CMOS technology to implement D-type flip-

flops. They possess high noise immunity, low power, and

speeds comparable to low power Schottky TTL circuits.

This device contains 8 master-slave flip-flops with a com-

mon clock and common clear. Data on the D input having

the specified setup and hold times is transferred to the Q

output on the LOW-to-HIGH transition of the CLOCK input.

The CLEAR input when LOW, sets all outputs to a low

state.

ground.

Features

■ Typical propagation delay: 18 ns

■ Wide operating voltage range

■ Low input current: 1 µA maximum

■ Low quiescent current: 80 µA (74 Series)

■ Output drive: 10 LS-TTL loads
