Product Summary
The SN74AHC157DR is a quadruple 2-line to 1-line data selector/multiplexer. The SN74AHC157DR is designed for 2-V to 5.5-V VCC operation. The SN74AHC157DR 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 devices provide true data.
