EVALUATION KIT AVAILABLE MAX22500E/MAX22501E 100Mbps Half-Duplex RS-485/RS-422
Transceivers for Long Cables General Description Benefits and Features The MAX22500E features integrated preemphasis circuitry
that extends the distance and increases the data rate of
reliable communication by reducing inter-symbol interference
(ISI) caused by long cables. The MAX22500E features a
flexible logic interface down to 1.6V. в—Џв—Џ Integrated Protection Increases Robustness -15V to +15V Common Mode Range В±15kV ESD Protection (Human Body Model) В±7kV IEC 61000-4-2 Air-Gap ESD Protection В±6kV IEC 61000-4-2 Contact Discharge ESD
Protection Driver Outputs are Short-Circuit Protected The MAX22500E/MAX22501E half-duplex ESD-protected
RS-485/RS-422 transceivers are optimized for highspeed (up to 100Mbps) communication over long cables.
These transceivers feature integrated hot-swap protection
and a fail-safe receiver, ensuring a logic-high on the
receiver output when input signals are shorted or open for
longer than 10Ојs (typ). The MAX22501E operates without preemphasis and is
powered from a 3V to 5.5V supply.
The MAX22500E is available in a 10-pin TDFN-EP package.
The MAX22501E is available in a 8-pin TDFN-EP package.
Both transceivers operate over the -40В°C to +125В°C ambient
temperature range. Applications в—Џв—Џ Motion Control в—Џв—Џ High-Speed Operation Over Long Distances Up to 100Mbps Data Rate Integrated Preemphasis Extends Cable Length
