3 Description
Thissingle 2-lineto 1-linedata selectormultiplexer is
designed for1.65-V to5.5-V VCC operation.
The SN74LVC2G157 device features a common
strobe (G) input. Whenthe strobe is high, Y is low
and Y is high. When the strobeis low, asingle bitis
selected from one of two sources and is routed to the
outputs. The device providestrue andcomplementary
data.
NanoFree™ package technology isa major
breakthrough in ICpackaging concepts, using thedie
as the package.
This device is fully specied for partial-power-down
applications using Io. The Io circuitry disablesthe
outputs, preventing damaging current backow
through the device whenit ispowered down.
