MAX22503E

100Mbps Full-Duplex 3V/5V RS-485/RS-422 Transceiver with High EFT Immunity

100Mbps Full-Duplex 3V/5V RS-485/RS-422 Transceiver with High EFT Immunity in SOIC 14 package


Please check latest availability status for a specific part variant.

Description

The MAX22503E full-duplex, ESD-protected, RS-485/RS-422 transceiver for high-speed communication operates up to 100Mbps. This transceiver features larger receiver hysteresis for high noise rejection and improved signal integrity. 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 MAX22503E is available in 14-pin SOIC package and operates over the -40°C to +125°C ambient temperature range.
