TS3A44159PWR from Texas Instruments, in a TSSOP-16. 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 | NO2 | bidirectional | Normally-Open analog switch terminal for channel 2. Analog signal range 0 V to VCC; on-state resistance ~0.45 Ω typical. Bidirectional analog I/O. |
| 2 | COM2 | bidirectional | Common analog terminal for channel 2. Connected to either NO2 or NC2 under control of IN1-2. Bidirectional, 0 V to VCC signal range. |
| 3 | NC2 | bidirectional | Normally-Closed analog switch terminal for channel 2. Connected to COM2 when IN1-2 is low. Bidirectional analog I/O, 0 V to VCC. |
| 4 | GND | power_in | Ground reference for the device. Continuous current through GND rated to 100 mA (absolute maximum). |
| 5 | NO3 | bidirectional | Normally-Open analog switch terminal for channel 3. Bidirectional, 0 V to VCC signal range; ~0.45 Ω typical Ron. |
| 6 | COM3 | bidirectional | Common analog terminal for channel 3. Connected to either NO3 or NC3 under control of IN3-4. |
| 7 | NC3 | bidirectional | Normally-Closed analog switch terminal for channel 3. Connected to COM3 when IN3-4 is low. |
| 8 | IN3-4 | input | Digital control input for channels 3 and 4. Selects COM to NO (high) or COM to NC (low). VIH ≥ 1 V, 1.8-V logic compatible; must not float. |
| 9 | NO4 | bidirectional | Normally-Open analog switch terminal for channel 4. Bidirectional, 0 V to VCC signal range. |
| 10 | COM4 | bidirectional | Common analog terminal for channel 4. Connected to either NO4 or NC4 under control of IN3-4. |
| 11 | NC4 | bidirectional | Normally-Closed analog switch terminal for channel 4. Connected to COM4 when IN3-4 is low. |
| 12 | VCC | power_in | Positive supply rail. Recommended operating range 1.65 V to 4.3 V (absolute max 4.6 V). Sets the analog signal range and the digital input clamp level. |
| 13 | NO1 | bidirectional | Normally-Open analog switch terminal for channel 1. Bidirectional, 0 V to VCC signal range. |
| 14 | COM1 | bidirectional | Common analog terminal for channel 1. Connected to either NO1 or NC1 under control of IN1-2. |
| 15 | NC1 | bidirectional | Normally-Closed analog switch terminal for channel 1. Connected to COM1 when IN1-2 is low. |
| 16 | IN1-2 | input | Digital control input for channels 1 and 2. Selects COM to NO (high) or COM to NC (low). VIH ≥ 1 V, 1.8-V logic compatible; must not float. |
