The MAX22506E ESD-protected RS-485/RS-422 transceiver is optimized for high-speed communication up to 50Mbps. This transceiver features 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 10μs (typ). Additionally, a large receiver hysteresis improves noise rejection and signal integrity.

The MAX22506E is designed to operate in harsh industrial environments and is optimized for robust communication in environments with high levels of electromagnetic interference (EMI).

The MAX22506E is available in an 8-pin SOIC and an 8-pin μMAX package. The transceiver operates over the -40°C to +125°C temperature range.
