MAX3283E/MAX3284E ±15kV ESD-Protected 52Mbps, 3V to 5.5V,
SOT23 RS-485/RS-422 True Fail-Safe Receivers General Description Benefits and Features 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. ●● ESD Protection: ±15kV Human Body Model ±6kV IEC 1000-4-2, Contact Discharge ±12kV IEC 1000-4-2, Air-Gap Discharge
●● Guaranteed 52Mbps Data Rate
●● Guaranteed 15ns Receiver Propagation Delay 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. ●● Guaranteed 2ns Receiver Skew 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 …
