MM74HC244

Octal 3-STATE Buffer

General Description

The MM74HC244 is a non-inverting buffer and has two

Features

■ Typical propagation delay: 14 ns

active low enables (1G and 2G); each enable indepen-

■ 3-STATE outputs for connection to system buses

■ Wide power supply range: 2–6V

dently controls

4 buffers. This device does not have

Schmitt trigger inputs.

■ Low quiescent supply current: 80

■ Output current: 6 mA

These 3-STATE buffers utilize advanced silicon-gate

CMOS technology and are general purpose high speed

non-inverting buffers. They possess high drive current out-

puts which enable high speed operation even when driving

large bus capacitances. These circuits achieve speeds

comparable to low power Schottky devices, while retaining

the advantage of CMOS circuitry, i.e., high noise immunity,

and low power consumption. All three devices have a

fanout of 15 LS-TTL equivalent inputs.

All inputs are protected from damage due to static dis-

charge by diodes to V_CCand ground.
