RS2105XTDC10 from Jiangsu RUNIC Tech, in a TDFN-10-EP(3x3). 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 | V+ | power_in | Positive power supply input. Operating range 1.8 V to 5.5 V (absolute max 7.0 V referenced to GND). Quiescent supply current typ <1 µA. |
| 2 | NO1 | passive | Normally-Open analog terminal of switch 1. Connected to COM1 when IN1 = logic high. Signal range 0 V to V+, continuous current ±500 mA, peak ±800 mA. |
| 3 | COM1 | passive | Common terminal of switch 1. Routes to NO1 when IN1 = 1, or to NC1 when IN1 = 0. On-resistance 0.6 Ω typ at V+ = 5 V. |
| 4 | IN1 | input | Digital control input for switch 1 (TTL/CMOS compatible). VIH ≥ 1.5 V (V+ = 5 V) or ≥ 1.3 V (V+ = 3.3 V); VIL ≤ 0.6 V / 0.5 V respectively. Unused inputs must be tied to V+ or GND. |
| 5 | NC1 | passive | Normally-Closed analog terminal of switch 1. Connected to COM1 when IN1 = logic low. Signal range 0 V to V+. |
| 6 | GND | power_in | Ground reference for supply and digital control logic. |
| 7 | NC2 | passive | Normally-Closed analog terminal of switch 2. Connected to COM2 when IN2 = logic low. Signal range 0 V to V+. |
| 8 | IN2 | input | Digital control input for switch 2 (TTL/CMOS compatible). Same thresholds as IN1. Unused inputs must be tied to V+ or GND. |
| 9 | COM2 | passive | Common terminal of switch 2. Routes to NO2 when IN2 = 1, or to NC2 when IN2 = 0. On-resistance 0.6 Ω typ at V+ = 5 V. |
| 10 | NO2 | passive | Normally-Open analog terminal of switch 2. Connected to COM2 when IN2 = logic high. Signal range 0 V to V+. |
