TCAN337DCNR

Texas Instruments · CAN Transceivers · SOT-23-8

TCAN337DCNR from Texas Instruments, in a SOT-23-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 TXD input CAN transmit data input; LOW for dominant and HIGH for recessive bus states; integrated pull up.
2 GND power_in Ground connection.
3 VCC power_in 3.3V supply voltage; recommended operating range 3.0 to 3.6V.
4 RXD tri_state CAN receive data output; LOW for dominant and HIGH for recessive bus states; tri-state output.
5 FAULT output Open drain fault output pin; activates on TXD-Dominant Timeout, RXD dominant Timeout, Thermal Shutdown or Undervoltage Lockout.
6 CANL bidirectional Low level CAN bus line; ±14V total bus pin fault protection; ±25kV HBM ESD protection.
7 CANH bidirectional High level CAN bus line; ±14V total bus pin fault protection; ±25kV HBM ESD protection.
8 S input Drive high for silent mode; integrated pull down.
