3 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.
