HD74LS151
1-of-8 Data Selector / Multiplexer (with strobe)
REJ03D0497-0300 Rev.3.00 May 10, 2006 This data selector / multiplexer contains full-on chip binary decoding to select the desired data source. The HD74LS151 selects one-of-eight data sources and has a strove input, which must be at a low logic level to enable this device. A high level at the strove forces the W output high, and the Y output low.
