DESCRIPTION
The AC541 is an advanced CMOS OCTAL BUS
BUFFER (3-STATE) fabricated with sub-micron
silicon gate and double-layer metal wiring C²MOS
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.
