SIT3051ESA

SIT · CAN Controllers · SOP-8

SIT3051ESA from SIT, 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 D input CAN transmit data input (TXD / driver input). LOW drives the bus dominant; HIGH leaves the bus recessive. Internally pulled up to VCC.
2 GND power_in Ground reference for the device. All voltages are referenced to this pin.
3 VCC power_in Transceiver supply voltage, 3.3V nominal (3.0V to 3.6V range). Absolute max -0.3V to +6V.
4 R output CAN receive data output (RXD / driver output). LOW for dominant bus state, HIGH for recessive. Output current limits ±11 mA.
5 SHDN input Shutdown input, CMOS/TTL compatible. Drive HIGH to enter low-current off mode; internal pull-down to GND keeps the device active if left open. VIH ≥ 2V, VIL ≤ 0.8V.
6 CANL bidirectional Low-level CAN bus line. Differential bus I/O with common-mode range -7V to +12V and >±12kV HBM ESD protection. Absolute max -36V to +36V; transient ±100V.
7 CANH bidirectional High-level CAN bus line. Differential bus I/O with common-mode range -7V to +12V and >±12kV HBM ESD protection. Absolute max -36V to +36V; transient ±100V.
8 RS input Mode select pin. Strong pull-down to GND (<0.33 VCC) selects high-speed mode; strong pull-up to VCC (>0.75 VCC) selects low-power/standby mode; a 10 kΩ to 100 kΩ pull-down to GND selects slope-control mode with adjustable driver transition times.

  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: sit3051esa-etched.step / sit3051esa-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sit3051esa.step / sit3051esa.glb are the bare package body.

Provenance

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

  • Datasheet: SIT datasheet (18 pp, sha256 6d6af5f032b778e0, retrieved 2026-08-17, tier: lcsc)
  • 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).
