鹵15kV ESD-Protected, Isolated, 3.3V
RS-485/RS-422 Data Interfaces
General Description
The MAX3480EA/MAX3480EB are electrically isolated
RS-485/RS-422 data-communications interfaces. The
RS-485/RS-422 I/O pins are protected against 鹵15kV
electrostatic discharge (ESD) shocks, without latchup.
Transceivers, optocouplers, and a transformer are all
included in one low-cost, 28-pin DIP package. A single
+3.3V supply on the logic side powers both sides of the
interface.
The MAX3480EB features reduced-slew-rate drivers
that minimize EMI and reduce reflections caused by
improperly terminated cables, allowing error-free data
transmission at data rates up to 160kbps. The
MAX3480EA鈥檚 driver slew rate is not limited, allowing
transmission rates up to 2.5Mbps.
Drivers are short-circuit current limited and are protect-
ed against excessive power dissipation by thermal
shutdown circuitry that places the driver outputs into a
high-impedance state. The receiver input has a fail-safe
feature that guarantees a logic-high output if the input
is open circuit.
The MAX3480EA/MAX3480EB are guaranteed to with-
stand 1260V
RMS
(1min) or 1520V
RMS
(1s). Their isolated
inputs and outputs meet RS-485/RS-422 specifications.
