This document describes the features and characteristics of the SN54AHC157 and SN74AHC157 quadruple 2-line to 1-line data selectors/multiplexers.
The document describes the SN54AHC157 and SN74AHC157 devices, which are quadruple 2-line to 1-line data selectors/multiplexers designed for 2-V to 5.5-V operation. These devices feature a common strobe (G) input that controls the routing of a 4-bit word from one of two sources to the four outputs.
| Supply voltage range | 2 V to 5.5 V |
|---|---|
| Operating temperature range (SN54AHC157) | -55°C to 125°C |
The devices are designed for 2-V to 5.5-V operation.
When the strobe is high, all outputs are low. When the strobe is low, a 4-bit word is selected and routed to the outputs.
