TS3A4742DGKR from Texas Instruments, in a VSSOP-8-0.65mm. 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 analog switch terminal for channel 1, connected to COM1 when IN1 is low. |
| 2 | COM1 | bidirectional | Common analog switch terminal for channel 1, which connects to NC1 under control of IN1. |
| 3 | IN2 | input | Digital control input for channel 2 that selects whether COM2 connects to NC2. |
| 4 | GND | power_in | Ground reference; the datasheet references VCC and all switch and digital voltages to GND, and the absolute maximum VCC is -0.3 V to 4 V relative to GND. |
| 5 | NC2 | unconnected | Normally closed analog switch terminal for channel 2, connected to COM2 when IN2 is low. |
| 6 | COM2 | bidirectional | Common analog switch terminal for channel 2, which connects to NC2 under control of IN2. |
| 7 | IN1 | input | Digital control input for channel 1 that selects whether COM1 connects to NC1; the digital input range is 0 to VCC. |
| 8 | VCC | power_in | Single power supply input, specified for 1.6 V to 3.6 V relative to GND, to be sequenced on before NC or COM signals are applied. |
