The MAX13442E/MAX13444E are fault-protected RS-485
and J1708 transceivers that feature ±80V protection from
signal faults on communication bus lines. The
MAX13442E/MAX13444E feature a reduced slew-rate driver
that minimizes EMI and reflections, allowing error-free
transmission up to 250kbps. The MAX13443E driver can
transmit up to 10Mbps. The high-speed MAX13443E
RS-485 tranceiver features ±60V protection from signal
faults on communication bus lines. These transceivers feature
foldback current limit. Each device contains one differential
line driver with three-state output and one
differential line receiver with three-state input. The 1/4-unit-load
receiver input impedance allows up to 128 transceivers
on a single bus. The devices operate from a 5V
supply. True fail-safe inputs guarantee a logic-high receiver
output when the receiver inputs are open, shorted, or
connected to an idle data line.
Hot-swap circuitry eliminates false transitions on the
data bus during circuit initialization or connection to a
live backplane. Short-circuit current-limiting and thermal-shutdown circuitry protect the driver against excessive
power dissipation, and on-chip ±15kV ESD
protection eliminates costly external protection devices.
The MAX13442E/MAX13443E/MAX13444E are available
in an 8-pin SO package and are specified over the
automotive temperature range.
