TCAN1042HGVDRQ1

Texas Instruments · CAN Controllers · SOIC-8

TCAN1042HGVDRQ1 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 local protocol controller. Low drives the bus to the dominant state; high (or floating, internally pulled to VIO/VCC) allows the bus to be recessive. Threshold referenced to VIO on 'V' devices.
2 GND power_in Device ground reference. Connect to system ground; bus-fault protection and common-mode voltages are measured with respect to this pin.
3 VCC power_in Transceiver 5 V supply (recommended 4.5 V to 5.5 V). Bypass with a low-ESR ceramic capacitor (typically 100 nF) close to the pin. UVLO removes the transceiver from the bus when VCC is below the undervoltage threshold.
4 RXD output CAN receive data output to the local protocol controller. Low when the bus is dominant, high when the bus is recessive. Output level is referenced to VIO on 'V' devices (this HGV part) and to VCC on non-'V' devices.
5 VIO power_in I/O level-shift supply (present only on 'V' suffix devices such as HGV). Sets the digital input thresholds (TXD, STB) and RXD output level to match a 3.3 V or 5 V MCU. Bypass with a 100 nF ceramic capacitor close to the pin.
6 CANL bidirectional Low-side CAN bus I/O line. Together with CANH forms the differential CAN bus. Withstands ±70 V bus fault (H-suffix) and ±30 V common-mode. Terminate the bus with 120 Ω at each end.
7 CANH bidirectional High-side CAN bus I/O line. Together with CANL forms the differential CAN bus. Withstands ±70 V bus fault (H-suffix) and ±30 V common-mode.
8 STB input Standby mode control input, active high. Low selects normal mode (transmitter and receiver active); high places the device in low-power standby with remote-wake pattern detection on the bus. Threshold referenced to VIO on 'V' devices.
