Physical-layer transceiver between a CAN or CAN FD controller and the bus, running from a single 3.3 V supply in a small SOT-23-8. TXD and RXD face the controller, CANH and CANL the bus, and an S pin selects normal or a low-current standby with bus wakeup. It meets ISO 11898-2 at data rates to 5 Mbps and tolerates the wide bus common-mode and ESD that industrial and automotive wiring demand. A compact 3.3 V CAN FD front end for space-limited boards.

Pinout

Pin	Name	Type	Function
1	TXD	input	CAN transmit data input from the controller. LOW drives a dominant bus state, HIGH allows recessive. Integrated pull-up to VCC prevents bus dominant if left floating. Driver dominant time-out (TXD DTO) limits stuck-dominant faults.
2	GND	power_in	Device ground reference. All logic and bus voltages referenced to this terminal.
3	VCC	power_in	3.3 V single supply input (recommended range 3.0-3.6 V, absolute max 5 V). Undervoltage protection places the device in a protected state below ~2 V.
4	RXD	output	CAN receive data output to the controller. LOW indicates dominant bus, HIGH indicates recessive. Tri-state (high-impedance) when device is unpowered or in low-power modes. Includes receiver dominant time-out (RXD DTO).
5	SHDN	input	Shutdown mode control input for TCAN330. Drive HIGH to enter ultra-low-power shutdown mode (bus and logic pins high-impedance). Internal pull-down keeps the device in normal mode if left open.
6	CANL	bidirectional	Low-side CAN bus I/O. Together with CANH forms the differential CAN pair. ±14 V bus fault protection and ±12 kV IEC 61000-4-2 contact-discharge ESD protection to GND.
7	CANH	bidirectional	High-side CAN bus I/O. Together with CANL forms the differential CAN pair. ±14 V bus fault protection and ±12 kV IEC 61000-4-2 contact-discharge ESD protection to GND.
8	S	input	Silent mode select input for TCAN330. Drive HIGH to disable the transmitter (listen-only silent mode); receiver remains active and mirrors bus traffic on RXD. Integrated pull-down defaults the device to normal mode.
