DESCRIPTION
The ACT541 is an advanced CMOS OCTAL BUS
BUFFER (3-STATE) fabricated with sub-micron
silicon gate and double-layer metal wiring C
2
MOS
technology.It is ideal for low power applications
mantaining high speed operation similar to
eqivalent 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.
The device is designed to interface directly High
Speed CMOS systems with TTL, NMOS and
CMOS output voltage levels.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
