MAX3281EAUT+T

The MAX3280E/MAX3281E/MAX3283E/MAX3284E
are single receivers designed for RS-485 and RS-422
communication. These devices guarantee data rates
up to 52Mbps, even with a 3V power supply. Excellent
propagation delay (15ns max) and package-to-package
skew time (8ns max) make these devices ideal for
multidrop 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 compatibility 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 VL in the range from 1.65V to
VCC. The MAX3284E is also offered in a 6-pin SOT23
package.
