3 Description

The SN74AHC157-Q1 is a quadruple 2-line to 1-line

data selectors/multiplexers are designed for 2-V to

5.5-V VCC operation. The SN74AHC157-Q1 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 device provides true

data.
