Overview
The SN74HC151PWR is an 8-line to 1-line data selector/multiplexer produced by Texas Instruments. This component is part of the HC series, known for its high-speed CMOS logic. It provides full binary decoding to select one of eight data sources and offers complementary outputs. The device is controlled by a strobe input (G), which must be at a low logic level to enable the inputs. A high level at the strobe terminal forces the standard output (Y) low and the inverted output (W) high.
