3PEAK · CAN Transceivers · SOP-8

TPT1042Q-SO1R-S from 3PEAK, in a SOP-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, HIGH for recessive); if TXD stays LOW longer than tTXD_DTO (2 ms typical, 5 ms maximum), the transmitter is disabled.
2	GND	power_in	Ground reference for the transceiver.
3	VCC	power_in	Transceiver 5 V supply voltage, recommended 4.5 V to 5.5 V (absolute maximum range −0.3 V to 7 V).
4	RXD	output	CAN receive data output (LOW for dominant, HIGH for recessive); output current is limited to −8 mA to 8 mA absolute maximum.
5	NC	unconnected	Not connected on the TPT1042Q; the VIO pin exists only on the V-suffix variant, and VIO is tied to VCC internally on this device.
6	CANL	bidirectional	Low-level CAN bus input/output line, with bus fault protection of −70 V to +70 V.
7	CANH	bidirectional	High-level CAN bus input/output line, with bus fault protection of −70 V to +70 V.
8	STB	input	Standby mode control input (active high): HIGH selects low-power standby, LOW selects normal mode, with VIH of 0.7 × VIO to VIO + 0.3 V.
