Overview
The SN74HC151DRG4 is a 8-line to 1-line data selector/multiplexer produced by Texas Instruments. This integrated circuit is part of the 74HC series and is designed to provide full binary decoding to select one of eight data sources. The device operates with a single supply voltage ranging from 2 V to 6 V, making it versatile for various applications. The strobe (G) input must be at a low logic level to enable the inputs, and a high level at the strobe terminal forces the W output high and the Y output low.
