TCAN1043ADRQ1

Texas Instruments · CAN Transceivers · SOIC-14

TCAN1043ADRQ1 from Texas Instruments, in a SOIC-14. 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 referenced to VIO with integrated 40-80kΩ pull-up resistor
2 GND power_in Ground connection; establish low-impedance return path to PCB ground plane
3 VCC power_in 5V transceiver power supply; requires 100nF bypass capacitor for stable operation
4 RXD tri_state CAN receive data output referenced to VIO; tri-states when VIO falls below UVIO(F) threshold
5 VIO power_in I/O power supply (1.7V to 5.5V range) for digital interface voltage matching; requires 100nF bypass capacitor
6 EN input Mode control enable input with integrated 40-80kΩ pull-down resistor; logic referenced to VIO
7 INH tri_state High-voltage inhibit output sourcing VSUP level; drives system regulator enable pin, open-drain design, sources 6mA maximum
8 nFAULT tri_state Active-low fault status output referenced to VIO; indicates device faults and remote/local wake-up events
9 WAKE input High-voltage local wake-up input (-45V to +45V, limited to VSUP+0.3V maximum); bi-directional edge triggered
10 VSUP power_in High-voltage battery power supply (4.5V to 40V nominal); supports ±58V transients and 300ms load-dump events
11 NC unconnected No connection; internally unconnected, leave floating
12 CANL bidirectional CAN low differential line; I/O pin with ±58V fault tolerance and 25-50kΩ receiver impedance
13 CANH bidirectional CAN high differential line; I/O pin with ±58V fault tolerance and 25-50kΩ receiver impedance
14 nSTB input Standby mode control input with integrated 40-80kΩ pull-down resistor; logic referenced to VIO
