Overview
The CD74HCT14M96E4 is a high-speed CMOS logic hex inverting Schmitt trigger IC produced by Texas Instruments. This device is part of the HCT series, which is compatible with both LSTTL (Low-power Schottky Transistor-Transistor Logic) and CMOS (Complementary Metal-Oxide-Semiconductor) input logic. It operates within a voltage range of 4.5V to 5.5V and is designed for a wide operating temperature range from -55°C to +125°C.
The CD74HCT14M96E4 features six independent inverters, each with Schmitt-trigger inputs, which provide hysteresis to improve noise immunity. This makes the device suitable for various applications requiring stable and reliable signal inversion.
