MM74HCT240 • MM74HCT244

Inverting Octal 3-STATE Buffer • Octal 3-STATE Buffer

General Description

The MM74HCT240 and MM74HCT244 3-STATE buffers

utilize advanced silicon-gate CMOS technology and are

general purpose high speed inverting and non-inverting

buffers. They possess high drive current outputs which

enable high speed operation even when driving large bus

capacitances. These circuits achieve speeds comparable

to low power Schottky devices, while retaining the low

power consumption of CMOS. All three devices are TTL

input compatible and have a fanout of 15 LS-TTL equiva-

lent inputs.

MM74HCT devices are intended to interface between TTL

and NMOS components and standard CMOS devices.

These parts are also plug-in replacements for LS-TTL

devices and can be used to reduce power consumption in

existing designs.

Ordering Code:

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

The MM74HCT240 is an inverting buffer and the

MM74HCT244 is a non-inverting buffer. Each device has

two active low enables (1G and 2G), and each enable inde-

pendently controls 4 buffers.

All inputs are protected from damage due to static dis-

charge by diodes to V

Features

TTL input compatible

Typical propagation delay: 14 ns

3-STATE outputs for connection to system buses

Low quiescent current: 80

High output drive current: 6 mA (min)
