The MAX22507E/MAX22508E ESD-protected RS-485/RS-422 full duplex transceivers are optimized for high-speed communication up to 50Mbps. 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 10µs (typ). Additionally, a large receiver hysteresis improves noise rejection and signal integrity.

The MAX22507E/MAX22508E are designed to operate in harsh industrial environments and are optimized for robust communication in environments with high levels of electromagnetic interference (EMI).

The MAX22507E is available in a 10-pin µMAX package and the MAX22508E is available in an 8-pin SOIC package. µMAX is the Maxim-trademarked equivalent to the industry-standard MSOP package. Both transceivers operate over the -40°C to +125°C temperature range.
