TC7SB3157CFU from TOSHIBA, 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 | B2 | passive | Switch port B2 connects to the A port when S selects B2; switch I/O voltage is limited to 0 to VCC in operation and switch I/O current to 50 mA absolute maximum. |
| 2 | GND | power_in | Ground reference for the device; the VCC/ground current is rated at ±100 mA absolute maximum. |
| 3 | B1 | passive | Switch port B1 connects to the A port when S selects B1; switch I/O voltage is limited to 0 to VCC in operation and switch I/O current to 50 mA absolute maximum. |
| 4 | A | passive | Common switch port A, which is routed to B1 or B2 depending on the S input; switch I/O voltage is limited to 0 to VCC in operation. |
| 5 | VCC | power_in | Supply voltage of 1.65 to 5.5 V (absolute maximum 7.0 V), and unused inputs and bus inputs must be tied to VCC or GND. |
| 6 | S | input | Select control input with an absolute maximum of -0.5 to 7.0 V and an operating range of 0 to 5.5 V, where VIH is at least 0.8×VCC (1.65-1.95 V supply) or 0.7×VCC (2.3-5.5 V supply) and VIL is at most 0.2×VCC or 0.3×VCC respectively. |
