Overview
The CD74HCT14M96G4, produced by Texas Instruments, is a high-speed CMOS logic hex inverting Schmitt trigger. This device contains six independent inverters, each with Schmitt-trigger inputs, which perform the Boolean function Y = A in positive logic. It is designed to operate within a voltage range of 4.5 V to 5.5 V and is compatible with both LSTTL and CMOS input logic. The device is known for its significant power reduction compared to traditional LSTTL logic ICs and its wide operating temperature range of -55°C to +125°C.
