LT1796 Overvoltage Fault Protected CAN Transceiver Features s s DESCRIPTIO s s s s s s s U APPLICATIO S s s s Protected from Overvoltage Line Faults to ±60V ESD Protection to IEC-1000-4-2 Level 4 ±15k V Air Gap Test ±8k V Contact Mode Test ISO 11898 patible High Input Impedance Supports Up to 256 Nodes Controlled Slew Rates for EMI Emissions Control High Impedance Outputs When Off or Powered Down Short-Circuit Protection On All Outputs Thermal Shutdown Protection Pin patible with Philips PCA82C251 The LT®1796 CAN transceiver provides built-in fault tolerance to survive in industrial and automotive environments. Discrete protection devices are not needed. Bus interface pins can withstand voltage faults up to ± 60V with respect to ground with no damage to the device. Faults may occur while the transceiver is active, shut down or powered off. On-chip ESD protection withstands up to ±15k V air discharges and ± 8k V contact mode discharges tested per IEC-1000-4-2. Loss of power or ground connections does not damage the IC. The circuit operates with data rates up to 125kbaud. A slew control pin allows control of transmitted data pulse edges to control EMI and reflection problems on imperfectly terminated lines. High output current drive allows the use of inexpensive PVC cable with impedance as low as 72Ω. The 100kΩ input impedance allows up to 256 transceivers per data network. The LT1796 is available in 8-lead PDIP and SO packages. , LTC and LT are registered trademarks of Linear Technology Corporation.
