DESCRIPTION

The 74AC541 is an advanced high-speed CMOS

OCTAL BUS BUFFER (3-STATE) fabricated with

sub-micron silicon gate and double-layer metal

wiring C2MOS tecnology.

The 3 STATE control gate operates as two inputs

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

74AC541 offers a pinout having inputs and

outputs on opposite sides of the package.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
