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 C
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.

ORDER CODES
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.
