MAX33623.3V, High-Speed, RS-485/RS-422
Transceiver in SOT Package
General Description
The MAX3362 low-power, high-speed transceiver for
RS-485/RS-422 communication operates from a single
+3.3V power supply. The device contains one differen-
tial transceiver consisting of a line driver and receiver.
The transceiver operates at data rates up to 20Mbps,
with an output skew of less than 6ns. Driver and receiv-
er propagation delays are guaranteed below 50ns. This
fast switching and low skew make the MAX3362 ideal
for multidrop clock/data distribution applications.
The output level is guaranteed at +1.5V with a standard
54Ωload, compliant with RS-485 specifications. The
transceiver draws 1.7mA supply current when
unloaded or fully loaded with the drivers disabled.
Additionally, the MAX3362 has a low-power shutdown
mode, reducing the supply current to 1µA.
The MAX3362 has a 1/8-unit-load receiver input imped-
ance, allowing up to 256 transceivers on the bus. The
MAX3362 is designed for half-duplex communication.
The device has a hot-swap feature that eliminates false
transitions on the data cable during circuit initialization.
The drivers are short-circuit current limited, and a ther-
mal shutdown circuit protects against excessive power
dissipation.
The MAX3362 is available in an 8-pin SOT package
and specified over industrial and automotive tempera-
ture ranges.

Note 1:Devices production tested at +25°C. Over-temperature limits are guaranteed by design.
Note 2:All currents into the device are positive; all currents out of the device are negative. All voltages are referenced to device
ground, unless otherwise noted.
Note 3:ΔVODand ΔVOCare the changes in VODand VOC, respectively, when the DI input changes state.
Note 4:The short-circuit output current applies to peak current just prior to foldback-current limiting; the short-circuit foldback out-
put current applies during current limiting to allow a recovery from bus contention.
Note 5:Shutdown is enabled by bringing REhigh and DE low. If the enable inputs are in this state for less than 50ns, the device is
guaranteed not to enter shutdown. If the enable inputs are in this state for at least 600ns, the device is guaranteed to have
entered shutdown.
Note 6:Transition time from shutdown mode to normal operation.
