Product Introduction

Overview

The 74HCT125D/AUJ, produced by Nexperia USA Inc., is a quad buffer/line driver with 3-state outputs. This device is part of the 74HCT series, which is known for its compatibility with TTL (Transistor-Transistor Logic) input levels. The 74HCT125D/AUJ features four independent buffer gates, each with a separate enable pin that controls the output state. When the enable pin is driven high, the corresponding output assumes a high impedance state, making it ideal for applications requiring output control.

The device operates over a wide supply voltage range from 4.5V to 5.5V, making it versatile for various electronic designs. It is also characterized by its low power consumption, high noise immunity, and robust ESD protection.
