Product Overview

The ADM1485JRZ is a 5V low power Differential Line Transceiver suitable for high speed bidirectional data communication on multipoint bus transmission lines. It is designed for balanced data transmission and complies with both RS-485 and RS-422 EIA standards. The part contains a differential line driver and a differential line receiver. The ADM1485 operates from a single 5V power supply. Excessive power dissipation caused by bus contention or by output shorting is prevented by a thermal shutdown circuit. This feature forces the driver output into a high impedance state if, during fault conditions, a significant temperature increase is detected in the internal driver circuitry. Up to 32 transceivers may be connected simultaneously on a bus, but only one driver should be enabled at any time. It is important, therefore, that the remaining disabled drivers do not load the bus. To ensure this, the ADM1485 driver features high output impedance when disabled and also when powered down.
  • 30Mbps Data rate
  • High speed, low power BiCMOS
  • Thermal shutdown protection
  • Short-circuit protection
  • 10ns Driver propagation delay
  • 15ns Receiver propagation delay
  • High-Z outputs with power-OFF
  • Superior upgrade for LTC1485
