MAX22502E
EVALUATION KIT AVAILABLE
100Mbps Full-Duplex RS-485/RS-422 Transceiver for Long Cables
General Description
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).
