General Description
The MAX3430 fault-protected RS-485 transceiver features
±
80V protection from overvoltage signal faults on commu-
nication bus lines. Each device contains one driver and
one receiver, and the output pins can withstand faults,
with respect to ground, of up to ±80V. Even if the faults
occur when the transceiver is active, shut down, or pow-
ered off, the device will not be damaged. The MAX3430
operates from a 3.3V supply and features a slew-rate-lim-
ited driver that minimizes EMI and reduces reflections
caused by improperly terminated cables, allowing error-
free data transmission at data rates up to 250kbps. The
MAX3430 has a 1/4-unit-load receiver input impedance
allowing up to 128 transceivers on a single bus and fea-
tures fail-safe circuitry, which guarantees a logic-high
receiver output when the receiver inputs are open.
Hot-swap circuitry eliminates false transitions on the
data cable 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.
The MAX3430 is available in 8-pin SO and 8-pin PDIP
packages, and is specified over commercial and indus-
trial temperature ranges.
