EVALUATION KIT AVAILABLE MAX14783E High-Speed 3.3V/5V RS-485/RS-422 Transceiver with 35kV HBM ESD Protection General Description Benefits and Features Integrated Protection Increases Robustness The MAX14783E is a half-duplex RS-485/422 transceiver High ESD Protection that operates at either 3.3V or 5V rails with high 35kV 35kV HBM ESD per JEDEC JS-001-2012 ESD performance and up to 42Mbps data rate. The 20kV Air Gap per IEC 61000-4-2 device is optimized for high speeds over extended cable 12kV Contact ESD per IEC 61000-4-2 runs while maximizing tolerance to noise. Short-Circuit Protected Outputs The MAX14783E is available in 8-pin MAX , 8-pin SO, and 8-pin TDFN-EP packages. The device in the TDFN-EP True Fail-Safe Receiver Prevents False Transition package operates over the -40C to +125C temperature on Receiver Input Short or Open Events range. The MAX14783E in the MAX and SO packages Hot-Swap Capability Eliminates False Transitions operates over the -40C to +85C and -40C to +125C During Power-Up or Hot Insertion temperature ranges. 3V to 5.5V Supply Voltage Range Applications High-Speed Data Rates up to 42Mbps Motion Controllers -40C to +125C Operating Temperature Field Bus Networks Allows Up to 32 Transceivers on the Bus Encoder Interfaces Low 10A (max) Shutdown Current for Lower Power Backplane Busses Consumption Ordering Information appears at end of data sheet.
