SL3088EESA from Slkor SLKORMICRO Elec, in a SOP-8. 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. |
