Description

The 74LCX125 device is a low-voltage CMOS

quad bus buffer manufactured with sub-micron

silicon gate and double-layer metal wiring C2MOS

technology. It is ideal for low-power and highspeed

3.3 V applications and can be interfaced to

a 5 V signal environment for both inputs and

outputs.

The device requires the 3-state control input G to

be set high to place the output in the high

impedance state.

It has the same speed performance at 3.3 V as

the 5 V AC/ACT family, combined with lower

power consumption.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2 kV ESD immunity and transient excess

voltage.
