TP3485ES8

TECH PUBLIC · RS-485 / RS-422 ICs · SOP-8

TP3485ES8 from TECH PUBLIC, 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 RO output Receiver output: with /RE low, RO is high if A-B ≥ -10mV and low if A-B ≤ -200mV.
2 /RE input Receiver output enable: drive low to enable RO, high makes RO high impedance; /RE high with DE low enters low-power shutdown.
3 DE input Driver output enable: drive high to enable driver outputs, low makes them high impedance; DE low with /RE high enters low-power shutdown.
4 DI input Driver input: with DE high, a low on DI forces non-inverting output low and inverting output high, and a high on DI does the opposite.
5 GND power_in Ground.
6 A bidirectional Non-inverting receiver input and non-inverting driver output.
7 B bidirectional Inverting receiver input and inverting driver output.
8 VCC power_in Positive supply, operating range 3.0 to 5.5V (absolute maximum 7V).

CAD (KiCad official)

  • Symbol: TP3485ES8
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: tp3485es8-etched.step / tp3485es8-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tp3485es8.step / tp3485es8.glb are the bare package body.
