SP3082EEN-L

MaxLinear · RS-485 / RS-422 ICs · SOIC-8

SP3082EEN-L from MaxLinear, in a SOIC-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 RO output Receiver output: with RE low, RO is high when A-B ≥ -40mV and low when A-B ≤ -200mV, and it is high-impedance when RE is high.
2 RE input Receiver output enable: RO is enabled when RE is low and goes high-impedance when RE is high; RE is a hot-swap input, and driving RE high with DE low puts the device into shutdown.
3 DE input Driver output enable: the driver outputs are enabled when DE is high and high-impedance when DE is low; DE is a hot-swap input, and driving DE low with RE high puts the device into shutdown.
4 DI input Driver input: with DE high, a low on DI forces the outputs low (A) and high (B), and a high on DI forces A high and B low.
5 GND power_in Ground reference for the device supply.
6 A bidirectional Noninverting receiver input and noninverting driver output on the RS-485 bus; ESD-protected to ±15kV (HBM and air-gap) and ±8kV contact discharge per IEC 61000-4-2.
7 B bidirectional Inverting receiver input and inverting driver output on the RS-485 bus; ESD-protected to ±15kV (HBM and air-gap) and ±8kV contact discharge per IEC 61000-4-2.
8 VCC power_in Positive supply for the single 5.0V supply operation; bypass to GND with a 0.1µF capacitor.
