**Texas Instruments** · Analog Switches, Multiplexers · SOIC-8

TS12A4516DR from Texas Instruments, in a SOIC-8. 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 | COM | bidirectional | Common analog switch terminal carrying rail-to-rail signals from V- to V+ with maximum continuous current ±20 mA |
| 2 | N.C. | unconnected | Not internally connected |
| 3 | N.C. | unconnected | Not internally connected |
| 4 | V+ | power_in | Positive power supply with dual-supply operation from +1 V to +6 V referenced to V- |
| 5 | N.C. | unconnected | Not internally connected |
| 6 | IN | input | Digital control input with logic threshold V+ - 1.5 V (HIGH) and V- to V+ - 3.5 V (LOW) connecting COM to NO |
| 7 | V- | power_in | Negative power supply with dual-supply operation from -1 V to -6 V referenced to V+ |
| 8 | NO | bidirectional | Normally open analog switch terminal connecting to COM when input IN is HIGH with ON-state resistance 25 Ω maximum at ±5 V supply |
