SN54LS157 四路 2 线路至 1 线路数据选择器/多路复用器

These monolithic data selectors/multiplexers contain inverters and drivers to supply full on-chip data selection to the four output gates. A separate strobe input is provided. A 4-bit word is selected from one of two sources and is routed to the four outputs. The ’157, ’LS157, and ’S157 present true data whereas the ’LS158 and ’S158 present inverted data to minimize propagation delay time.
