Texas Instruments · Analog Switches, Multiplexers · TSSOP-14

SN74LV4066APWR from Texas Instruments, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1A bidirectional Input/Output to switch channel 1
2 1B bidirectional Input/Output to switch channel 1
3 2B bidirectional Input/Output to switch channel 2
4 2A bidirectional Input/Output to switch channel 2
5 2C input Control line for channel 2; switch is ON when control pin is high
6 3C input Control line for channel 3; switch is ON when control pin is high
7 GND power_in Ground (0V) reference
8 3A bidirectional Input/Output to switch channel 3
9 3B bidirectional Input/Output to switch channel 3
10 4B bidirectional Input/Output to switch channel 4
11 4A bidirectional Input/Output to switch channel 4
12 4C input Control line for channel 4; switch is ON when control pin is high
13 1C input Control line for channel 1; switch is ON when control pin is high
14 VCC power_out Positive power supply; connect a decoupling capacitor ranging from 0.1µF to 10µF between VCC and GND for reliable operation
