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 ±15kV air
discharges and ±8kV 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.
