TCAN1051HDR

Texas Instruments · CAN Controllers · SOIC-8

TCAN1051HDR 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 TXD input CAN transmit data input from the MCU. LOW drives the bus dominant; HIGH lets the bus recess. Internal pull-up to VCC.
2 GND power_in Device ground reference (0 V).
3 VCC power_in Transceiver 5-V supply voltage (nominal 4.5-5.5 V). Bypass with a 100 nF ceramic to GND close to the pin.
4 RXD output CAN receive data output to the MCU. LOW when the bus is dominant, HIGH when the bus is recessive. Driven to VCC on non-'V' variants.
5 NC unconnected No connect. On non-'V' suffix variants (including TCAN1051H) pin 5 is unused and should be left floating or tied to GND.
6 CANL bidirectional Low-side CAN bus I/O line. Differential pair with CANH. ±70 V bus fault protection and ±30 V common-mode range on H variants.
7 CANH bidirectional High-side CAN bus I/O line. Differential pair with CANL. ±70 V bus fault protection and ±30 V common-mode range on H variants.
8 S input Silent (listen-only) mode control input, active HIGH. Tie LOW (or to GND) for normal transmit/receive operation; drive HIGH to disable the transmitter and remain a passive bus listener.

  • 3D model files: tcan1051hdr-etched.step / tcan1051hdr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tcan1051hdr.step / tcan1051hdr.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (37 pp, sha256 9d4561ff8b0892f7, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
