description/ordering information

These quadruple 2-line to 1-line data selectors/multiplexers are designed for 2-V to 5.5-V VCC operation. The ’AHC157 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.
