MAXIM INTEGRATED / ANALOG DEVICES MAX3490CPA RS-485 Transceiver

The MAX3490CPA is a 3.3V-powered RS-485/RS-422 transceiver supporting data rates up to 10 Mbps. It features short-circuit current limiting and thermal overload protection via shutdown circuitry that places outputs into high impedance. Operating from 3V to 3.6V within 0°C to 70°C, it includes one driver and one receiver with fail-safe high output when inputs are open. Supporting full duplex, with enable pins for both driver and receiver, it allows up to 32 transceivers on a bus and is compatible with +5V logic levels. Ideal for industrial communication, it handles common mode voltages from -7V to +12V and is used extensively in industrial networks and telecom applications. Delivery is affected by extended lead times, with no discounts applicable.
