Quadruple 2-Line To 1-Line Data Selectors/Multiplexer

SN54F157A, SN74F157A QUADRUPLE 2ĆLINE TO 1ĆLINE DATA SELECTORS/MULTIPLEXERS ą SDFS053A − MARCH 1987 − REVISED OCTOBER 1993 • Buffered Inputs and Outputs • Package Options Include Plastic Small-Outline Packages, Ceramic Chip Carriers, and Standard Plastic and Ceramic 300-mil DIPs description The ′F157A is a quadruple 2-input data selector/multiplexer featuring a common strobe (G) input. When the strobe is high, all outputs are low. When the strobe is low, a 4-bit word is selected from one of two sources and is routed to the four outputs. The ′F157A provides true data. The SN54F157A is characterized for operation over the full military temperature range of − 55°C to 125°C. The SN74F157A is characterized for operation from 0°C to 70°C.
