Product Introduction

Overview

The 74HC14D is a high-speed CMOS Schmitt Trigger Inverter fabricated with silicon gate C2MOS technology. Produced by Toshiba Semiconductor and Storage, this integrated circuit is designed to achieve high-speed operation similar to equivalent LSTTL (Low Power Schottky Transistor-Transistor Logic) while maintaining the low power dissipation characteristic of CMOS devices. The 74HC14D is pin-compatible with the 74HC04D but features inputs with 25% VCC hysteresis, making it suitable for receiving slow input signals and enhancing noise immunity.
