2 RE input Receiver enable, active low (2-MΩ internal pull-up)
3 DE input Driver enable, active high (2-MΩ internal pull-down)
4 D input Driver data input
5 GND power_in Device ground
6 A bidirectional Bus I/O port, A (complementary to B)
7 B bidirectional Bus I/O port, B (complementary to A)
8 VCC power_in 3.3-V to 5-V supply
9 Thermal Pad passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: THVD1450DRBT
  • Footprint: Package_SON:WSON-8-1EP_3x3mm_P0.5mm_EP1.6x2.0mm
  • 3D model: SON-8-EP(3x3) (KiCad packages3D, STEP)
  • 3D model files: thvd1450drbt-etched.step / thvd1450drbt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); thvd1450drbt.step / thvd1450drbt.glb are the bare package body.
