3.3V, 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
54鈩?load, 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 1碌A.
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.
