MAX3280E/MAX3281E/ ±15kV ESD-Protected 52Mbps, 3V to 5.5V, MAX3283E/MAX3284E SOT23 RS-485/RS-422 True Fail-Safe Receivers General Description Benefits and Features
The MAX3280E/MAX3281E/MAX3283E/MAX3284E ● ESD Protection: are single receivers designed for RS-485 and RS-422 ±15kV Human Body Model communication. These devices guarantee data rates ±6kV IEC 1000-4-2, Contact Discharge up to 52Mbps, even with a 3V power supply. Excellent ±12kV IEC 1000-4-2, Air-Gap Discharge propagation delay (15ns max) and package-to-package ● Guaranteed 52Mbps Data Rate skew time (8ns max) make these devices ideal for multidrop clock distribution applications. ● Guaranteed 15ns Receiver Propagation Delay The MAX3280E/MAX3281E/MAX3283E/MAX3284E ● Guaranteed 2ns Receiver Skew have true fail-safe circuitry, which guarantees a logic-high ● Guaranteed 8ns Package-to-Package Skew Time receiver output when the receiver inputs are opened ● V or shorted. The receiver output will be a logic high if L Pin for Connection to FPGAs/ASICs all transmitters on a terminated bus are disabled (high ● Allow Up to 128 Transceivers on the Bus impedance). These devices feature 1/4-unit-load receiver (1/4-unit-load) input impedance, allowing up to 128 receivers on the ● Tiny SOT23 Package same bus. ● True Fail-Safe Receiver The MAX3280E is a single receiver available in a 5-pin ● -7V to +12V Common-Mode Range SOT23 package. The MAX3281E/MAX3283E single receivers have a receiver enable (EN or EN) function and ● 3V to 5.5V Power-Supply Range are offered in a 6-pin SOT23 package. The MAX3284E ● Enable (High and Low) Pins for Redundant Operation features a voltage logic pin that allows compatibility with ● Three-State Output Stage (MAX3281E/MAX3283E) low-voltage logic levels, as in digital FPGAs/ASICs. On the MAX3284E, the voltage threshold for a logic high ● Thermal Protection Against Output Short Circuit is user-defined by setting VL in the range from 1.65V to ● AEC-Q100 (MAX3280EAUK/V+ Only) VCC. The MAX3284E is also offered in a 6-pin SOT23
