MAX22507E/MAX22508E 50Mbps Full-Duplex RS-485/RS-422 Transceivers with High EFT Immunity General Description Benefits and Features The MAX22507E/MAX22508E ESD-protected RS-485/ High-Speed Operation Over Long Distances RS-422 full-duplex transceivers are optimized for high- Up to 50Mbps Data Rate speed communication up to 50Mbps. These transceivers High Receiver Sensitivity feature integrated hot-swap protection and a fail-safe re- Wide Receiver Bandwidth ceiver, ensuring a logic-high on the receiver output when Symmetrical Receiver Thresholds input signals are shorted or open for longer than 10s Integrated Protection Increases Robustness (typ). Additionally, a large receiver hysteresis improves -15V to +15V Common Mode Range noise rejection and signal integrity. 15kV ESD Protection (Human Body Model) The MAX22507E/MAX22508E are designed to operate in 7kV IEC 61000-4-2 Air-Gap ESD Protection harsh industrial environments and are optimized for robust 6kV IEC 61000-4-2 Contact Discharge ESD communication in environments with high levels of electro- Protection magnetic interference (EMI). Withstands Over 4kV EFT Driver Outputs are Short-Circuit Protected The MAX22507E is available in a 10-pin MAX package and the MAX22508E is available in an 8-pin SOIC pack- Flexibility for Many Different Applications age.

Note that a +, , or - in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing pertains to the package regardless of RoHS status. Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.
