SN54F151B, SN74F151B 1-OF-8 DATA SELECTORS/MULTIPLEXERS SDFS023A – D2932, MARCH 1987 – REVISED OCTOBER 1993 • • SN54F151B . . . J PACKAGE SN74F151B . . . D OR N PACKAGE (TOP VIEW) 8-Line to 1-Line Multiplexers Can Perform as: Boolean Function Generators Parallel-to-Serial Converters Data Source Selectors Package Options Include Plastic Small-Outline Packages, Ceramic Chip Carriers, and Standard Plastic and Ceramic 300-mil DIPs D3 D2 D1 D0 Y W G GND description These monolithic data selectors/multiplexers provide full binary decoding to select one of eight data sources. The strobe (G) input must be at a low logic level to enable the data selection/multiplexing function. A high level at the strobe terminal forces the W output high and the Y output low. 1 16 2 15 3 14 4 13 5 12 6 11 7 10 8 9 VCC D4 D5 D6 D7 A B C D2 D3 NC VCC D4 SN54F151B . . .
