DESCRIPTION/ORDERING INFORMATION
This single 2-line to 1-line data selector/multiplexer is designed for 1.65-V to 5.5-V VCC operation.
The SN74LVC2G157 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.

(2) DCT: The actual top-side marking has three additional characters that designate the year, month, and assembly/test site.
DCU: The actual top-side marking has one additional character that designates the assembly/test site.
YZP: The actual top-side marking has three preceding characters to denote year, month, and sequence code, and one following
character to designate the assembly/test site. Pin 1 identifier indicates solder-bump composition (1 = SnPb, • = Pb-free).
