Description

General part information

SN74AHCT157-Q1 Series

These quadruple 2-line to 1-line data selectors/multiplexers are designed for 4.5V to 5.5V VCC operation.

The SN74AHCT157-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 devices provide true data.

These quadruple 2-line to 1-line data selectors/multiplexers are designed for 4.5V to 5.5V VCC operation.
