This quadruple 2-line to 1-line data selector/multiplexer is designed for 4.5-V to 5.5-V VCC operation. The 74ACT157 features 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 device provides true data.
