SN74LVC2G157DCUR

Texas Instruments · Signal Switches, Multiplexers, Decoders · VSSOP-8-0.5mm

SN74LVC2G157DCUR from Texas Instruments, in a VSSOP-8-0.5mm. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A input Data input A; routed to output when A/B=low and G=low.
2 B input Data input B; routed to output when A/B=high and G=low.
3 Y output Inverted output; high when G=high or selected input=low.
4 GND power_in Ground (0V reference).
5 Y output True output; low when G=high or selected input=low.
6 A/B input Input selector; high selects B input, low selects A input when G=low.
7 G input Strobe input; high forces Y=low and Y=high, low enables data routing.
8 VCC power_out Positive supply voltage; 1.65V to 5.5V operating range.
