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.
