description/ordering information

This quadruple 2-line to 1-line data selector/multiplexer is designed for 1.5-V to 5.5-V VCC operation.

The CD74AC158 features a common strobe (G) input. When the strobe is high, all outputs are high. When the

strobe is low, a 4-bit word is selected from one of two sources and is routed to the four outputs. This device

provides inverted data.
