# SL8022KS

**Slkor(SLKORMICRO Elec.)** · Touch Screen Controllers · SOP-8

SL8022KS from Slkor(SLKORMICRO Elec.), in a SOP-8. 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 | OSC | input | Functional option input whose level (VDD or GND) before power-on sets the initial LO1/LO2 output state: high if connected to VDD, low if connected to GND. |
| 2 | VC | input | Sampling capacitor input; capacitor between VC and GND (e.g. 0.01uF for 3mm acrylic) sets touch sensitivity. |
| 3 | VDD | power_in | Positive power supply, 2.4V to 5.5V. |
| 4 | GND | power_in | Negative power supply (ground). |
| 5 | TI1 | input | Touch input for channel 1, whose touch operation reverses the logic output on LO1. |
| 6 | TI2 | input | Touch input for channel 2, whose touch operation reverses the logic output on LO2. |
| 7 | LO1 | output | Control output for channel 1, toggled by a touch on TI1 and reverting to its initial state on release. |
| 8 | LO2 | output | Control output for channel 2, toggled by a touch on TI2 and reverting to its initial state on release. |

## CAD (KiCad official)

- Symbol: `SL8022KS`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `sl8022ks-etched.step` / `sl8022ks-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sl8022ks.step` / `sl8022ks.glb` are the bare package body.
