RS2268XQ from Jiangsu RUNIC Tech, in a TSSOP-14. 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 | 1IN | input | Channel 1 switch-enable input; the switch is disabled when IN is low and COM connects to NO when IN is high, with VINH and VINL limits of 1.5 V and 0.6 V at 5 V supply. |
| 2 | 1COM | passive | Channel 1 common terminal, an input or output that passes signals equally well in either direction. |
| 3 | 1NO | passive | Channel 1 normally-open terminal, an input or output that passes signals equally well in either direction. |
| 4 | 2IN | input | Channel 2 switch-enable input; the switch is disabled when IN is low and COM connects to NO when IN is high, with VINH and VINL limits of 1.5 V and 0.6 V at 5 V supply. |
| 5 | 2COM | passive | Channel 2 common terminal, an input or output that passes signals equally well in either direction. |
| 6 | 2NO | passive | Channel 2 normally-open terminal, an input or output that passes signals equally well in either direction. |
| 7 | GND | power_in | Ground reference; unused digital inputs must be held at VIO or GND for proper device operation. |
| 8 | 3NO | passive | Channel 3 normally-open terminal, an input or output that passes signals equally well in either direction. |
| 9 | 3COM | passive | Channel 3 common terminal, an input or output that passes signals equally well in either direction. |
| 10 | 3IN | input | Channel 3 switch-enable input; the switch is disabled when IN is low and COM connects to NO when IN is high, with VINH and VINL limits of 1.5 V and 0.6 V at 5 V supply. |
| 11 | 4NO | passive | Channel 4 normally-open terminal, an input or output that passes signals equally well in either direction. |
| 12 | 4COM | passive | Channel 4 common terminal, an input or output that passes signals equally well in either direction. |
| 13 | 4IN | input | Channel 4 switch-enable input; the switch is disabled when IN is low and COM connects to NO when IN is high, with VINH and VINL limits of 1.5 V and 0.6 V at 5 V supply. |
| 14 | V+ | power_in | Power supply, rated 1.8 V to 5.5 V (absolute maximum 6 V). |
