Product Overview: 74HC125 Quad Buffer/Line Driver from NXP

The 74HC125 from NXP Semiconductors is a high-speed Si-gate CMOS device that is designed to deliver the functionality of a quad buffer/line driver with 3-state outputs. Each buffer has a separate output enable (OE) input which, when high, disables the output by placing it in a high impedance state. This feature makes the 74HC125 ideal for interfacing with bus lines in a bus-oriented system.
