description
This quadruple 2-line to 1-line data selector/multiplexer is designed for 1.65-V to 3.6-V V
CC
operation.
The SN74LVC157A 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 device
provides true data.
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators
in a mixed 3.3-V/5-V system environment.
The SN74LVC157A is characterized for operation from –40
