3 Description
This single 2-line to 1-line data selector multiplexer is
designed for 1.65-V to 5.5-V V_CC 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 I_off. The I_off circuitry disables the
outputs, preventing damaging current backflow
through the device when it is powered down.
