SN74F157A 四路 2 线路至 1 线路数据选择器/多路复用器
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
