SL3088EESA

Slkor SLKORMICRO Elec · RS-485 / RS-422 ICs · SOP-8

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.

CAD (KiCad official)

  • Symbol: SL3088EESA
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: sl3088eesa-etched.step / sl3088eesa-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sl3088eesa.step / sl3088eesa.glb are the bare package body.

Provenance
