TS3A4751PWR 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 | NO1 | passive | Channel 1 normally-open analog switch terminal. Bidirectional signal path connected to COM1 when IN1 is high. Handles rail-to-rail analog signals within 0 V to VCC, up to 100 mA continuous current. |
| 2 | COM1 | passive | Channel 1 common analog switch terminal. Bidirectional signal path connected to NO1 when IN1 is high. Handles rail-to-rail analog signals within 0 V to VCC. |
| 3 | NO2 | passive | Channel 2 normally-open analog switch terminal. Bidirectional signal path connected to COM2 when IN2 is high. Handles rail-to-rail analog signals within 0 V to VCC. |
| 4 | COM2 | passive | Channel 2 common analog switch terminal. Bidirectional signal path connected to NO2 when IN2 is high. Handles rail-to-rail analog signals within 0 V to VCC. |
| 5 | IN2 | input | Logic control input for channel 2. Drives high (VIH ≥ 1.4 V @ 3-V supply, ≥ 1.0 V @ 1.8-V supply) to close the switch between NO2 and COM2; low (VIL ≤ 0.5 V / 0.4 V) opens it. Input leakage ≤ ±10 nA. Can be driven up to 3.6 V regardless of VCC. |
| 6 | IN3 | input | Logic control input for channel 3. Drives high to close the switch between NO3 and COM3; low opens it. 1.8-V CMOS compatible with 3-V VCC. Input leakage ≤ ±10 nA over temperature. |
| 7 | GND | power_in | Ground reference. Continuous current through GND is rated ±100 mA maximum. All voltages are referenced to this pin. |
| 8 | NO3 | passive | Channel 3 normally-open analog switch terminal. Bidirectional signal path connected to COM3 when IN3 is high. Handles rail-to-rail analog signals within 0 V to VCC. |
| 9 | COM3 | passive | Channel 3 common analog switch terminal. Bidirectional signal path connected to NO3 when IN3 is high. Handles rail-to-rail analog signals within 0 V to VCC. |
| 10 | COM4 | passive | Channel 4 common analog switch terminal. Bidirectional signal path connected to NO4 when IN4 is high. Handles rail-to-rail analog signals within 0 V to VCC. |
| 11 | NO4 | passive | Channel 4 normally-open analog switch terminal. Bidirectional signal path connected to COM4 when IN4 is high. Handles rail-to-rail analog signals within 0 V to VCC. |
| 12 | IN4 | input | Logic control input for channel 4. Drives high to close the switch between NO4 and COM4; low opens it. 1.8-V CMOS compatible with 3-V VCC. Input leakage ≤ ±10 nA. |
| 13 | IN1 | input | Logic control input for channel 1. Drives high to close the switch between NO1 and COM1; low opens it. 1.8-V CMOS compatible with 3-V VCC. Input leakage ≤ ±10 nA. |
| 14 | VCC | power_in | Positive supply voltage, 1.6 V to 3.6 V single-supply operation (absolute max 4 V). Typical ICC is 0.05 µA. Decoupling with a 0.1-µF ceramic capacitor to GND is recommended. |
