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 | RO | output | Receiver Output. When /RE is low: RO=high if A−B ≥ −10mV; RO=low if A−B ≤ −200mV. High-impedance when /RE is high. VOH ≥ VCC−1.5V at IOUT=−2.5mA; VOL ≤ 0.4V at IOUT=+2.5mA. |+| 2 | /RE | input | Receiver Output Enable (active-low). Drive /RE low to enable RO; RO is high-impedance when /RE is high. Driving /RE high together with DE low enters low-power shutdown mode (ISHDN ≈ 0.2µA typ). |+| 3 | DE | input | Driver Output Enable (active-high). Drive DE high to enable driver outputs A and B; outputs are high-impedance when DE is low. Driving /RE high together with DE low enters low-power shutdown mode. |+| 4 | DI | input | Driver Input. With DE high, DI=low forces A low and B high; DI=high forces A high and B low. TTL/CMOS-compatible input (VIH=2.0V min, VIL=0.8V max). |+| 5 | GND | power_in | Ground reference for all voltages on the device. |+| 6 | A | bidirectional | Non-inverting Receiver Input and non-inverting Driver Output (RS-485 bus line A). Absolute input voltage rating −15V to +15V; 96kΩ receiver input impedance (1/8 unit load). |+| 7 | B | bidirectional | Inverting Receiver Input and inverting Driver Output (RS-485 bus line B). Absolute input voltage rating −15V to +15V; 96kΩ receiver input impedance (1/8 unit load). |+| 8 | VCC | power_in | Positive supply, 3.0V to 5.5V operating range (absolute max +6.5V). Bypass to GND close to the pin with a 0.1µF ceramic capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Slkor SLKORMICRO Elec |+| Package | SOP-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `SL3088EESA`+- `SL3088EEUA`+- `SL3088EEPA`+- `SL3088ETK`++## CAD (KiCad official)++- Symbol: `SL3088EESA`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Slkor SLKORMICRO Elec datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8603061139013967872) (None pp, sha256 `34727b1806c02f58`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
