Product Overview

The NM485DC is an electrically isolated dual differential EIA-485 Driver and Receiver designed for balanced multipoint bus transmission at rates up to 1.25Mbits per second. The device provides two receive channels and two driver channels. The two driver channels have an active high enable. No external components are needed and a single 5V input supply powers all functions either side of the isolation boundary. The driver outputs provide limiting for positive and negative currents and thermal shutdown protection from line fault conditions on the transmission bus line. The receiver outputs will always be high if the receiver inputs are open. The isolation voltage between input and output is 1000Vrms.
  • Thermal shutdown protection
  • EIA-485 and CCITT V.28 compatible
  • Driver tri-state outputs active high enable
  • RoHS compliant
