## Description

The SN65HVD251 is a CAN physical layer transceiver compliant with ISO 11898, enabling communication rates up to 1 Mbps. It features differential transmit/receive capability and robust protection against harsh environments (cross-wire, over-voltage, loss of ground, transients ±200V). It operates from a 4.5V to 7V supply.

## Electrical Characteristics

️· Supply Voltage: 4.5V - 7V
️· Input Resistance (CANH/CANL): 20-50kΩ
️· Output Voltage (Dominant): 2.75-4.5V
️· Standby Current: 200µA (typical)
️· ESD Protection: Exceeds 14kV (HBM)
️· Propagation Delay: 35-150ns (typical)

## Operating Modes

️· High-Speed: Achieved by grounding Rs pin.
️· Slope Control: Achieved with a resistor connected to Rs. (10kΩ = 15V/µs, 100kΩ = 2V/µs)
️· Low-Power/Standby: Achieved by applying a high logic to the Rs pin.

## Packages

️· 8-pin SOIC (D)
️· 8-pin DIP (P)
