SN65HVD3082EDR

Texas Instruments · RS-485 / RS-422 ICs · SOIC-8

SN65HVD3082EDR from Texas Instruments, in a SOIC-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 R output Receive data output (digital). Delivers the received differential bus data as a single-ended CMOS-level signal to the host UART/MCU.
2 RE input Receiver enable, active low. Drive low to enable the receiver output R; drive high to place R in high-impedance.
3 DE input Driver enable, active high. Drive high to enable the differential bus driver on A/B; drive low to place driver outputs in high-impedance.
4 D input Driver data input (digital). CMOS-level TX data from the host UART/MCU that is transmitted as a differential signal on A/B when the driver is enabled.
5 GND power_in Local device ground (reference potential, 0 V).
6 A bidirectional RS-485 differential bus I/O, non-inverting line. Driver output or receiver input, complementary to B. 15-kV ESD protected bus pin.
7 B bidirectional RS-485 differential bus I/O, inverting line. Driver output or receiver input, complementary to A. 15-kV ESD protected bus pin.
8 VCC power_in Positive supply input, 4.5 V to 5.5 V (5-V nominal). Bypass locally with a 100-nF ceramic to GND.

CAD (KiCad official)

  • Symbol: SN65HVD3082EDR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: sn65hvd3082edr-etched.step / sn65hvd3082edr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn65hvd3082edr.step / sn65hvd3082edr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sn65hvd3082edr.step 122 KB You want the bare part, or you mark your own boards.
sn65hvd3082edr-etched.step 3.0 MB You want the part with SN65HVD3082EDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 729 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (40 pp, sha256 5da24ada598efdc4, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
