# TPG4157C6

**TECH PUBLIC** · Analog Switches, Multiplexers · SOT-363

TPG4157C6 from TECH PUBLIC, in a SOT-363. 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 | B1 | passive | Independent input or output, connected to A when S is high. |
| 2 | GND | power_in | Ground (0 V). |
| 3 | B0 | passive | Independent input or output, connected to A when S is low. |
| 4 | A | passive | Common output or input, with a recommended signal voltage of -0.3 to 5.5 V. |
| 5 | VCC | power_in | Supply voltage, with a recommended operating range of 1.5 to 5.5 V. |
| 6 | S | input | Select input: low connects B0 to A and high connects B1 to A, with a control voltage of -0.3 to 5.5 V. |
