HMT232T from GATEMODE, in a SOP-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	D	input	CAN transmit data input (TXD). LOW drives a dominant bus state and HIGH drives a recessive bus state. Digital input voltage range -0.5V to VCC+0.5V.
2	GND	power_in	Ground connection / network ground reference terminal.
3	VCC	power_in	Transceiver supply voltage, 3.0V to 3.6V (nominal 3.3V). Absolute maximum 6V.
4	R	output	CAN receive data output (RXD). LOW for dominant and HIGH for recessive bus states. Drives VOH ≥ 2.4V at -8mA and VOL ≤ 0.4V at 8mA.
5	NC	unconnected	HMT232: No Connect. (On HMT230/HMT231 this pin is Vref, the VCC/2 reference output; not populated on the HMT232 variant.)
6	CANL	bidirectional	Low-level CAN bus line. Differential I/O with CANH; operates over -2V to 7V common-mode range and tolerates -40V to 40V at the bus terminal. ±16kV HBM ESD protection.
7	CANH	bidirectional	High-level CAN bus line. Differential I/O with CANL; operates over -2V to 7V common-mode range and tolerates -40V to 40V at the bus terminal. ±16kV HBM ESD protection.
8	NC	unconnected	HMT232: No Connect. (On HMT230/HMT231 this pin is Rs, the mode-select input for high-speed / slope-control / standby modes; not populated on the HMT232 variant.)
