SN65HVD251DR

Texas Instruments · CAN Transceivers · SOIC-8

SN65HVD251DR from Texas Instruments, in a SOIC-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, driver input). LOW drives a dominant bus state and HIGH allows the bus to go to the recessive state. Input voltage range: -0.3 V to VCC+0.5 V.
2 GND power_in Ground connection (device 0 V reference).
3 VCC power_in Transceiver 5-V supply voltage. Recommended operating range 4.5 V to 5.5 V.
4 R output CAN receive data output (RXD, receiver output). LOW for a dominant bus state and HIGH for a recessive bus state. Output current up to ±4 mA.
5 VREF output Reference output voltage, nominally VCC/2. Provides a stable mid-supply reference for use as a bias voltage to external circuitry.
6 CANL bidirectional Low-level CAN bus line. Differential bus I/O per ISO 11898. Absolute-max bus voltage ±36 V continuous, ±200 V transient (ISO 7637 pulses 1,2,3a,3b).
7 CANH bidirectional High-level CAN bus line. Differential bus I/O per ISO 11898. Absolute-max bus voltage ±36 V continuous, ±200 V transient (ISO 7637 pulses 1,2,3a,3b).
8 Rs input Mode select pin. Strong pulldown to GND selects high-speed mode; strong pull-up to VCC selects low-power standby mode; 10 kΩ to 100 kΩ pulldown to GND selects slope-control mode (10 kΩ ≈ 15 V/µs, 100 kΩ ≈ 2 V/µs slew rate).
