The MAX3080E–MAX3089E are ±15kV electrostatic discharge (ESD)-protected, high-speed transceivers for RS485/RS-422 communication that contain one driver and one receiver. These devices feature fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted. This means that the receiver output will be a logic hig.
independently programmable receiver and transmitter output phase via separate pins.
Features
o ESD Protection for RS-485 I/O Pins ±15kV, Human Body Model o True Fail-Safe Receiver While Maintaining EIA/TIA-485 Compatibility o Enhanced Slew-Rate Limiting Facilitates Error-Free Data Transmission (MAX3080E
–MAX3085E/MAX3089E) o 1nA Low-Current Shutdown Mode (Except MAX3081E/MAX3084E/MAX3087E) o Pin-Selectable Full/Half-Duplex Operation (MAX3089E) o Phase Controls to Correct for Twisted-Pair Reversal (MAX3089E) o Allow Up to 256 Transceivers on the Bus
