The MAX3280E/MAX3281E/MAX3283E/MAX3284E are
single receivers designed for RS-485 and RS-422 com-
munication. These devices guarantee data rates up to
52Mbps, even with a 3V power supply. Excellent propa-
gation delay (15ns max) and package-to-package
skew time (8ns max) make these devices ideal for mul-
tidrop clock distribution applications.
The MAX3280E/MAX3281E/MAX3283E/MAX3284E
have true fail-safe circuitry, which guarantees a logic-
high receiver output when the receiver inputs are
opened or shorted. The receiver output will be a logic
high if all transmitters on a terminated bus are disabled
(high impedance). These devices feature 1/4-unit-load
receiver input impedance, allowing up to 128 receivers
on the same bus.
The MAX3280E is a single receiver available in a 5-pin
SOT23 package. The MAX3281E/MAX3283E single
receivers have a receiver enable (EN or EN) function
and are offered in a 6-pin SOT23 package. The
MAX3284E features a voltage logic pin that allows com-
patibility with low-voltage logic levels, as in digital
FPGAs/ASICs. On the MAX3284E, the voltage threshold
for a logic high is user-defined by setting V
range from 1.65V to V
offered in a 6-pin SOT23 package.
