MAXIM MAX22508EASA+

The ESD-protected RS-485/RS-422 full-duplex transceivers are optimized for highspeed 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. They 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.
