DESCRIPTION
●The HVD251 is intended for use in applications employing the Controller Area Network (CAN) serial
●communication physical layer in accordance with the ISO 11898 Standard. The HVD251 provides
●differential transmit capability to the bus and differential receive capability to a CAN controller at speeds up to 1 megabits per second (Mbps).
●FEATURES
●• Drop-In Improved Replacement for the PCA82C250 and PCA82C251
●• Bus-Fault Protection of ±36 V
●• Meets or Exceeds ISO 11898
●• Signaling Rates(1) Up to 1 Mbps
●• High Input Impedance Allows up to 120 Nodes on a Bus
●• Bus Pin ESD Protection Exceeds 14 kV HBM
●• Unpowered Node Does Not Disturb the Bus
●• Low-Current Standby Mode — 200 µA Typical
●• Thermal Shutdown Protection
●• Glitch-Free Power-Up and Power-Down Bus Protection For Hot-Plugging
●• DeviceNet Vendor ID # 806
●(1)The signaling rate of a line is the number of voltage transitions that are made per second expressed in bps (bits per second).
●APPLICATIONS
●• CAN Data Buses
●• Industrial Automation
●• SAE J1939 Standard Data Bus Interface
●• NMEA 2000 Standard Data Bus Interface
