Overview
The CD74HCT151M96G4 is a high-speed CMOS logic 8-input digital multiplexer produced by Texas Instruments. This device is part of the CDx4HCT151 series and is designed to operate within the TTL-compatible voltage range. It features three binary control inputs (A, B, and C) and an active low enable (G) input, allowing it to select one of eight channels. The outputs are provided in both inverting (W) and non-inverting (Y) forms. This multiplexer is known for its balanced propagation delay and transition times, as well as its significant power reduction compared to traditional LSTTL logic ICs.
