open-in-new Find other Encoders & decoders

Description

This single 2-line to 1-line data selector multiplexer is designed for 1.65-V to 5.5-V VCC operation.

The SN74LVC2G157 device features a common strobe (G) input. When the strobe is high, Y is low and Y is high. When the strobe is low, a single bit is selected from one of two sources and is routed to the outputs. The device provides true and complementary data.

NanoFree™ package technology is a major breakthrough in IC packaging concepts, using the die as the package.

This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
