DESCRIPTION

The 74VHC541 is an advanced high-speed

CMOS

OCTAL

BUS

BUFFER

(3-STATE)

fabricated

with

sub-micron silicon gate and

The 3 STATE control gate operates as two input

AND such that if either G1 or G2 are high, all eight

outputs are in the high impedance state.

In order to enhance PC board layout, the

74VHC541 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.
