DESCRIPTION

The 74LCX540 is a low voltage CMOS OCTAL

BUS

BUFFER

(INVERTED)

fabricated

with

sub-micron silicon gate and double-layer metal

wiring C2MOS technology. It is ideal for low power

and high speed 3.3V applications; it can be

interfaced to 5V signal environment for both inputs

and outputs.

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 74LCX540

offers a pinout having inputs and outputs on

opposite sides of the package.

It has same speed performance at 3.3V than 5V

AC/ACT family, combined with a lower power

consumption.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
