Texas Instruments · Analog Switches, Multiplexers · SOT-23-5

SN74LVC1G66DBVT from Texas Instruments, in a SOT-23-5. 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 bidirectional Bidirectional signal to be switched; I/O port voltage range 0 to VCC with maximum 5.5V.
2 B bidirectional Bidirectional signal to be switched; I/O port voltage range 0 to VCC with maximum 5.5V.
3 GND power_in Ground pin; device reference potential.
4 C input Control input for analog switch; low level turns switch OFF and high level turns switch ON; accepts voltage 0 to 5.5V.
5 VCC power_in Power supply pin; recommended operating voltage range 1.65V to 5.5V.
