**Texas Instruments** · Analog Switches, Multiplexers · TSSOP-14

TS12A44515PWR from Texas Instruments, in a TSSOP-14. 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 | NC1 | unconnected | Normally closed terminal of switch 1, connected to COM1 when IN1 is low and usable as input or output over 0 V to VCC. |
| 2 | COM1 | bidirectional | Common terminal of switch 1, bidirectional analog signal over 0 V to VCC. |
| 3 | NC2 | unconnected | Normally closed terminal of switch 2, connected to COM2 when IN2 is low and usable as input or output over 0 V to VCC. |
| 4 | COM2 | bidirectional | Common terminal of switch 2, bidirectional analog signal over 0 V to VCC. |
| 5 | IN2 | input | Digital control input for switch 2 (low connects NC2 to COM2, high disconnects), with 0.8 V max VIL and 2.4 V min VIH at 5-V supply; should not be left floating. |
| 6 | IN3 | input | Digital control input for switch 3 (low connects NC3 to COM3, high disconnects), with 0.8 V max VIL and 2.4 V min VIH at 5-V supply; should not be left floating. |
| 7 | GND | power_in | Ground. |
| 8 | NC3 | unconnected | Normally closed terminal of switch 3, connected to COM3 when IN3 is low and usable as input or output over 0 V to VCC. |
| 9 | COM3 | bidirectional | Common terminal of switch 3, bidirectional analog signal over 0 V to VCC. |
| 10 | COM4 | bidirectional | Common terminal of switch 4, bidirectional analog signal over 0 V to VCC. |
| 11 | NC4 | unconnected | Normally closed terminal of switch 4, connected to COM4 when IN4 is low and usable as input or output over 0 V to VCC. |
| 12 | IN4 | input | Digital control input for switch 4 (low connects NC4 to COM4, high disconnects), with 0.8 V max VIL and 2.4 V min VIH at 5-V supply; should not be left floating. |
| 13 | IN1 | input | Digital control input for switch 1 (low connects NC1 to COM1, high disconnects), with 0.8 V max VIL and 2.4 V min VIH at 5-V supply; should not be left floating. |
| 14 | VCC | power_in | Power supply, 2 V to 12 V recommended operating range (13 V absolute maximum). |
