MAX22500E/MAX22501E 100Mbps Half-Duplex RS-485/RS-422 Transceivers for Long Cables General Description Benefits and Features The MAX22500E/MAX22501E half-duplex ESD-protected High-Speed Operation Over Long Distances RS-485/RS-422 transceivers are optimized for high-speed Up to 100Mbps Data Rate (up to 100Mbps) communication over long cables.These Integrated Preemphasis Extends Cable Length transceivers feature integrated hot-swap protection and a (MAX22500E) fail-safe receiver, ensuring a logic-high on the receiver High Receiver Sensitivity output when input signals are shorted or open for longer Wide Receiver Bandwidth than 10s (typ). Symmetrical Receiver Thresholds The MAX22500E features integrated preemphasis circuit- Integrated Protection Increases Robustness ry that extends the distance and increases the data rate of -15V to +15V Common Mode Range reliable communication by reducing inter-symbol interfer- 15kV ESD Protection (Human Body Model) ence (ISI) caused by long cables. The MAX22500E fea- 7kV IEC 61000-4-2 Air-Gap ESD Protection tures a flexible logic interface down to 1.6V. 6kV IEC 61000-4-2 Contact Discharge ESD Protection The MAX22501E operates without preemphasis and is Withstands up to 4kV EFT powered from a 3V to 5.5V supply. Driver Outputs are Short-Circuit Protected The MAX22500E is available in a 10-pin TDFN-EP pack- Flexibility for Many Different Applications age. The MAX22501E is available in a 8-pin TDFN-EP 3V to 5.5V Supply Range package and an 8-pin MAX package. Both transceivers Low Voltage Logic Supply Down to 1.6V operate over the -40C to +125C ambient temperature (MAX22500E) range. Low 5A (max) Shutdown Current Available in 8-pin or 10-pin TDFN Package and an Applications 8-pin MAX Package Motion Control -40C to +125C Operating Temperature Range Encoder Interfaces Field Bus Networks Ordering Information appears at end of data sheet.
