SN65HVD72DGKR

Texas Instruments · RS-485 / RS-422 ICs · VSSOP-8-0.65mm

SN65HVD72DGKR from Texas Instruments, in a VSSOP-8-0.65mm. 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. CMOS logic output presenting the recovered differential data from the A/B bus. High-Z when RE is deasserted (high).
2 RE input Active-low receiver enable. Drive low to enable the receiver output R; drive high to place R in high-impedance.
3 DE input Active-high driver enable. Drive high to enable the differential bus driver on A/B; drive low to place the driver outputs in high-impedance.
4 D input Driver data input. CMOS logic input carrying the transmit data to be driven differentially onto the A/B bus when DE is high.
5 GND power_in Local device ground / reference potential (0 V).
6 A bidirectional RS-485 differential bus I/O, complementary to B. Non-inverting driver output and non-inverting receiver input. Absolute max -13 V to +16.5 V; recommended common-mode range -7 V to +12 V.
7 B bidirectional RS-485 differential bus I/O, complementary to A. Inverting driver output and inverting receiver input. Absolute max -13 V to +16.5 V; recommended common-mode range -7 V to +12 V.
8 VCC power_in Supply voltage. 3 V to 3.6 V nominal (3.3 V typ). Bypass to GND with a 100 nF ceramic capacitor close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sn65hvd72dgkr.step 122 KB You want the bare part, or you mark your own boards.
sn65hvd72dgkr-etched.step 2.5 MB You want the part with SN65HVD72DGKR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 608 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 (47 pp, sha256 b46f5803fa8302f9, 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).
