PIN AND FUNCTION COMPATIBLE WITH

74 SERIES 540

LATCH-UP PERFORMANCE EXCEEDS

500mA (JESD 17)

ESD PERFORMANCE:

HBM > 2000V (MIL STD 883 method 3015);

MM > 200V

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.

DESCRIPTION

The 74LCX540 is a low voltage CMOS OCTAL

BUS BUFFER (INVERTED) fabricated with

sub-micron silicon gate and double-layer metal

wiring C MOS 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.
