HT82C251ARZ

HTCSEMI · Buffer/Driver/Transceiver · SOP-8

HT82C251ARZ from HTCSEMI, 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 Transmit data input from the CAN controller; low (~1 V) drives the bus dominant, high (~4 V) gives recessive, with VIH min 0.7 VCC and VIL max 0.3 VCC.
2 GND power_in Ground.
3 VCC power_in Supply voltage, 4.5 V to 5.5 V recommended operating range (absolute maximum 7.0 V).
4 RXD output Receive data output to the CAN controller; low when the bus is dominant (VDIFF > 0.9 V), high when recessive (VDIFF < 0.5 V).
5 Vref power_in Reference voltage output equal to half of the supply voltage (0.45 VCC to 0.55 VCC).
6 CANL bidirectional Low-level CAN bus line, with input/output voltage range of -36 V to 36 V and recessive bus voltage of 2.0 V to 3.0 V.
7 CANH bidirectional High-level CAN bus line, with input/output voltage range of -36 V to 36 V and recessive bus voltage of 2.0 V to 3.0 V.
8 RS input Mode select: grounded (VRs < 0.3 VCC) for high-speed, resistor Rext to ground for reduced-RFI slope control, and VRs > 0.75 VCC for standby.
