The SN74LVC157A quadruple 2-line to 1-line data selector/multiplexer is designed for 2.7-V to 3.6-V V_CC operation.

The device features a common strobe (G) input. When G is high, all outputs are low. When G 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 this device as a translator in a mixed 3.3-V/5-V system environment.
