MAX22508EASA+

MAX22508EASA+ is a 50Mbps full-duplex RS-485/RS-422 transceiver with high EFT immunity. This device is optimized for high-speed communication upto 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. It is designed to operate in harsh industrial environments and is optimized for robust communication in environments with high levels of electromagnetic interference (EMI). It is used in applications such as motion control, encoder interfaces, field bus networks, industrial control systems, backplane busses.
