LCX125Y Datasheet Low-voltage CMOS Quad Bus Buffer

Manufacturer: STMicroelectronics

Overview: 74LCX125 Low-voltage CMOS quad bus buffer (3-state) with 5 V tolerant inputs and outputs Datasheet −production.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General 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.
