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.

Product Details

The MAX22502E evaluation kit (EV kit) is a fully assembled and tested PCB that demonstrates the functionality of the MAX22502E and the MAX22503E full-duplex high speed RS-485/RS-422 transceiver. The EV kit includes on-board termination for easy point-to-point evaluation. The EV kit is assembled using MAX22502E in a 12-pin TDFN package, but also provides equivalent functional evaluation for the MAX22503E, which is offered in a 14-pin SOIC package.
