DESCRIPTION

The 74LVC244A is a low voltage CMOS OCTAL

BUS

BUFFER

(3-STATE)

fabricated

with

sub-micron silicon gate and double-layer metal

wiring C2MOS technology. It is ideal for 1.65 to 3.6

VCC operations and low power and low noise

applications.

It can be interfaced to 5V signal environment for

inputs in mixed 3.3/5V system.

G control output governs four BUS BUFFERs.

This device is designed to be used with 3 state

memory address drivers, etc.

It has more 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.
