DESCRIPTION

The AC541 is an advanced CMOS OCTAL BUS

BUFFER (3-STATE) fabricated with sub-micron

silicon gate and double-layer metal wiring C

technology. It is ideal for low power applications

mantaining high speed operation similar to

equivalent Bipolar Schottky TTL.

The 3 STATE control gate operates as a 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 AC541

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.
