DESCRIPTION
The 74ACT541 is an advanced high-speed CMOS
OCTAL BUS BUFFER (3-STATE) fabricated with
sub-micron silicon gate and double-layer metal
wiring C
2
MOS tecnology.
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.
