description/ordering information

These quadruple 2-line to 1-line data selectors/multiplexers are designed for 1.5-V to 5.5-V VCC operation.

The ’AC157 devices feature 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 devices

provide true data.
