description/ordering information
This quadruple 2-line to 1-line data selector/multiplexer is designed for 4.5-V to 5.5-V V_CC operation.
The CD74ACT157 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.
