General Description

The MM74HCT540 and MM74HCT541 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. Both devices are TTL input

compatible and have a fanout of 15 LS-TTL equivalent

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 MM74HCT540 is an inverting buffer and the

MM74HCT541 is a non-inverting buffer. The 3-STATE con-

trol gate operates as a two-input NOR such that if either G1

or G2 are HIGH, all eight outputs are in the high-imped-

ance state.

In order to enhance PC board layout, the MM74HCT540

and MM74HCT541 offers a pinout having inputs and out-

puts on opposite sides of the package. All inputs are pro-

tected from damage due to static discharge by diodes to

Features

TTL input compatible

Typical propagation delay: 12 ns

3-STATE outputs for connection to system buses

Low quiescent current: 80

Output current: 6 mA (min.)
