Features, Applications

The MAX14775E/MAX14776E fault-protected RS-485/ RS-422 transceivers feature 65V protection for overvoltage signal faults on communication bus lines, ensuring communication in harsh industrial environments. Each device contains one driver and one receiver and operates over the to 5.5V supply range. The MAX14775E is optimized for high-speed data rates to 20Mbps. The MAX14776E features slew-rate limited outputs for data rates to 500kbps. These transceivers are optimized for robust communication in noisy environments. A large 200mV (typ) hysteresis on receiver inputs ensure for high noise rejection and a failsafe feature guarantees a logic-high on the receiver output when the inputs are open or shorted. Driver outputs are protected against short-circuit conditions. The MAX14775E/MAX14776E receivers feature a 1/3unit load input impedance, allowing to 100 transceivers on a bus. The MAX14775E/MAX14776E are available in 8-pin SOIC and 8-pin TDFN-EP packages and operate over the to +125C temperature range.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
