HMT1040T

GATEMODE · CAN ICs · SOP-8

HMT1040T from GATEMODE, in a SOP-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 TXD input Transmit data input from the CAN protocol controller. TXD high drives the bus recessive; TXD low drives the bus dominant.
2 GND power_in Ground reference for the device. All non-differential voltages are referenced to this pin.
3 VCC power_in Supply voltage input, recommended 4.5 V to 5.5 V (absolute max 7 V). Powers the transceiver core and CAN bus driver.
4 RXD output Receive data output to the CAN protocol controller. RXD is high when the bus is recessive and low when the bus is dominant.
5 SPLIT output Common-mode stabilization output, nominally VCC/2 (0.3×VCC to 0.7×VCC for -500 µA < IO < 500 µA). Intended to bias the center tap of a split termination network.
6 CANL bidirectional Low-level CAN bus line. Differential CAN bus I/O with bus-fault protection from -50 V to +50 V.
7 CANH bidirectional High-level CAN bus line. Differential CAN bus I/O with bus-fault protection from -50 V to +50 V.
8 STB input Standby mode control input. STB low selects normal (high-speed) mode; STB high selects low-power standby with bus wake-up capability.

  • HMT1040TT

CAD (KiCad official)

  • Symbol: HMT1040T
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: hmt1040t-etched.step / hmt1040t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hmt1040t.step / hmt1040t.glb are the bare package body.

Provenance

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

  • Datasheet: GATEMODE datasheet (12 pp, sha256 043fd1e2b7d5f48d, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
