DESCRIPTION

The VHC541 is an advanced high speed CMOS

OCTAL BUS BUFFER (3-STATE) fabricated with

sub-micron silicon gate and double-layer metal

wiring C2MOS technology.

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.

Power down protection is provided on all inputs

and 0 to 7V can be accepted on inputs with no

regard to the supply voltage. This device can be

used to interface 5V to 3V.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
