MM74HCT273

Octal D-Type Flip-Flop with Clear

All inputs to this device are protected from damage due to

electrostatic discharge by diodes to V_CCand ground.

General Description

The MM74HCT273 utilizes advanced silicon-gate CMOS

technology. It has an input threshold and output drive simi-

lar to LS-TTL with the low standby power of CMOS.

MM74HCT devices are intended to interface TTL and

NMOS components to CMOS components. These parts

can be used as plug-in replacements to reduce system

power consumption in existing designs.

These positive edge-triggered flip-flops have a common

clock and clear-independent Q outputs. Data on a D input,

having the specified set-up and hold time, is transferred to

the corresponding Q output on the positive-going transition

of the clock pulse. The asynchronous clear forces all out-

puts LOW when it is LOW.

Features

■ Typical propagation delay: 20 ns

■ Low quiescent current: 80 µA maximum (74HCT series)

■ Fanout of 10 LS-TTL loads
