Single 2:1 multiplexer for mixed-voltage logic
The SN74LVC2G157DCUR is a single 2:1 multiplexer from the 74LVC family, routing one of two data inputs to a single output based on the select pin state. Output drive is rated 32 mA source and sink at the rated supply voltage, enough to drive a standard CMOS input plus a small LED or a short PCB trace without a buffer.
Housed in an 8-VFSOP (2.30 mm width) package, also designated 8-VSSOP as the supplier device package. The tape-and-reel (TR) or cut-tape (CT) options let you order production reels or prototype quantities. Surface-mount assembly with a typical MSL-1 floor life (no bake required before reflow) keeps the pick-and-place cycle simple. The narrow body means the part sits close to the MCU or FPGA it serves, minimising stub length on the select and data lines.
