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.
