HX65HVD251-S

ZHHXDZ · CAN Transceivers · SOP-8

HX65HVD251-S from ZHHXDZ, 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 D input Transmit data input; has a pull-up to VCC so the bus stays recessive when unpowered, with a dominant time-out timer, VIH min 2 V and VIL max 0.8 V.
2 GND power_in Ground supply.
3 VCC power_in Supply voltage, VCC=5V±10%.
4 R output Receive data output that reads out data from the bus lines; VOH min 4 V at IO=-2 mA and VOL max 0.4 V at 2 mA.
5 Vref power_in Common-mode stabilization output, 0.3VCC to 0.7VCC for load currents between -500 µA and 500 µA.
6 CANL bidirectional LOW-level CAN bus line, with bus-side voltage rating of -60 V to +60 V.
7 CANH bidirectional HIGH-level CAN bus line, with bus-side voltage rating of -60 V to +60 V.
8 Rs input High speed and standby mode selection; low (grounded) selects high speed, high or unconnected selects standby mode.
