ANALOG DEVICES MAX13442EASA+ Transceiver RS485, 4.75V-5.25V supply, 1 Driver, NSOIC-8

MAX13442EASA+ is a transceiver that features a reduced slew-rate driver that minimizes EMI and reflections, allowing error-free transmission up to 250kbps. The device operates from a 5V supply. True fail-safe inputs guarantee a logic-high receiver output when receiver inputs are open, shorted, or connected to an idle data line. Hot-swap circuitry eliminates false transitions on the data bus during circuit initialization or connection to a live backplane. Short-circuit current-limiting and thermal-shutdown circuitry protect the driver against excessive power dissipation, and on-chip ±15kV ESD protection eliminates costly external protection devices. Applications include RS-422/RS-485 communications, truck and trailer applications, industrial networks, telecommunications systems, automotive applications, and HVAC controls.
