DESCRIPTION
The VHCT541A is an advanced high speed
CMOS
OCTAL
BUS
fabricated with sub-micron silicon gate
double-layermetal wiring C
2
MOS technology.
The 3 STATE control gate operates as a two
BUFFER
(3-STATE)
and
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 sidesof the package.
Power down protection is provided on all inputs
and outputs and 0 to 7V can be accepted on
inputs with no regard to the supply voltage. This
device can be used to interface5V to 3V.
All
inputs
and
outputs are
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
