MAX3362
3.3V, High-Speed, RS-485/RS-422 Transceiver in
SOT Package

Detailed 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 line driver and one differential line receiver. The dri-
ver and receiver may be independently enabled. When
disabled, outputs enter a high-impedance state.
The transceiver guarantees data rates up to 20Mbps,
with an output skew of less than 6ns. This low skew
time makes the MAX3362 ideal for multidrop clock/data
distribution applications, such as cellular base stations.
Driver and receiver propagation delays are below 50ns.
The output level is guaranteed at 1.5V on a standard
54Ω load.
The device has a hot-swap feature that eliminates false
transitions on the data cable during circuit initialization.
Also, drivers are short-circuit current limited and are
protected against excessive power dissipation by ther-
mal shutdown circuitry.
