IMPROVED LATCH-UP IMMUNITY

DESCRIPTION

The 74ACT541 is an advanced high-speed CMOS

OCTAL BUS BUFFER (3-STATE) fabricated with

sub-micron silicon gate and double-layer metal

The 3 STATE control gate operates as two input

AND such that if either G1 and G2 are high, all

eight outputs are in the high impedance state.

In order to enhance PC board layout, the

74ACT541 offers a pinout having inputs and

outputs on opposite sides of the package.

This device is designed to interface directly High

Speed CMOS systems with TTL, NMOS and

CMOS output voltage levlels.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
