MM74HC540 • MM74HC541

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

General Description

The MM74HC540 and MM74HC541 3-STATE buffers uti-

lize advanced silicon-gate CMOS technology. They pos-

sess 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 advantage of CMOS

circuitry, i.e., high noise immunity, and low power consump-

tion. Both devices have a fanout of 15 LS-TTL equivalent

inputs.

The MM74HC540 is an inverting buffer and the

MM74HC541 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 MM74HC540 and

MM74HC541 offers a pinout having inputs and outputs on

opposite sides of the package. All inputs are protected from

damage due to static discharge by diodes to V

ground.

Ordering Code:

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