**Texas Instruments** · Analog Switches, Multiplexers · VSSOP-8-0.5mm

TS5A21366DCUR 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 | NO1 | passive | Switch 1 normally-open terminal, connected to COM1 when IN1 is HIGH. |
| 2 | COM1 | passive | Switch 1 common terminal, connected to NO1 when IN1 is HIGH and high impedance when IN1 is LOW. |
| 3 | IN2 | input | Switch 2 digital control pin: LOW gives a high-impedance path from NO2 to COM2, HIGH connects NO2 to COM2; input is 1.8-V compatible with control input voltage rated 0 V to 5.5 V. |
| 4 | GND | power_in | Digital ground reference for the device. |
| 5 | NO2 | passive | Switch 2 normally-open terminal, connected to COM2 when IN2 is HIGH. |
| 6 | COM2 | passive | Switch 2 common terminal, connected to NO2 when IN2 is HIGH and high impedance when IN2 is LOW. |
| 7 | IN1 | input | Switch 1 digital control pin: LOW gives a high-impedance path from NO1 to COM1, HIGH connects NO1 to COM1; input is 1.8-V compatible with control input voltage rated 0 V to 5.5 V. |
| 8 | VCC | power_in | Power supply, 1.65 V to 5.5 V recommended operating range. |
