    EVALUATION KIT AVAILABLE MAX22502E 100Mbps Full-Duplex RS-485/RS-422
    Transceiver for Long Cables General Description Benefits and Features The MAX22502E full-duplex, ESD-protected, RS-485/
    RS-422 transceiver is optimized for high-speed (up to
    100Mbps) communication over long cables.This transceiver
    features larger receiver hysteresis for high noise rejection
    and improved signal integrity. Integrated preemphasis
    circuitry extends the distance, and increases the data rate,
    of reliable communication by reducing inter-symbol
    interference (ISI) caused by long cables when supplied with
    5V. Integrated hot-swap protection and a fail-safe receiver
    ensure a logic-high on the receiver output when input signals
    are shorted or open for longer than 10μs (typ).
    The MAX22502E is available in a 12-pin TDFN-EP (3mm
    x 3mm) package and operates over the -40°C to +125°C
    ambient temperature range. Applications ●● Motion Control
    ●● Encoder Interfaces
    ●● Field Bus Networks
    ●● Industrial Control Systems ●● High-Speed Operation Over Long Distances Up to 100Mbps Data Rate Integrated Preemphasis Extends Cable Length High Receiver Sensitivity Wide Receiver Bandwidth Symmetrical Receiver Thresholds
    ●● Integrated Protection Increases Robustness -15V to +15V Common Mode Range ±15kV ESD Protection (Human Body Model) ±7kV IEC61000-4-2 Air-Gap ESD Protection ±6kV IEC61000-4-2 Contact Discharge
    ESD Protection Driver Outputs are Short-Circuit Protected
    ●● Flexibility for Many Different Applications 3V to 5.5V Supply Range Low Voltage Logic Supply Down to 1.6V Low 5µA (max) Shutdown Current Available in 12-pin TDFN (3mm x 3mm) Package -40°C to +125°C Operating Temperature Range
