General Description
The MAX3440E–MAX3444E fault-protected RS-485 and
J1708 transceivers feature
±60V protection from signal
faults on communication bus lines. 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 trans-
ceivers on a single bus. The devices operate from a 5V
supply at data rates of up to 10Mbps. 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 ther-
mal shutdown circuitry protect the driver against exces-
sive power dissipation, and on-chip
±15kV ESD
protection eliminates costly external protection devices.
The MAX3440E–MAX3444E are available in 8-pin SO
and PDIP packages and are specified over industrial
and automotive temperature ranges.
