DESCRIPTION/ORDERING INFORMATION
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 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.

Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at
www.ti.com/sc/package.
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.
YEA/YZA, YEP/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,
