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
