FEATURES
DESCRIPTIOU
The LT
1796 CAN transceiver provides built-in fault toler-
ance to survive in industrial and automotive environ-
ments. 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 con-
nections 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 72
.
The 100k
input impedance allows up to 256 transceivers
per data network.
The LT1796 is available in 8-lead PDIP and SO packages.
