Product Overview

The LTC1481CN8#PBF is an ultralow power differential Line Transceiver designed for data transmission standard RS485 applications. It will also meet the requirements of RS422. The CMOS design offers significant power savings over its bipolar counterparts without sacrificing ruggedness against overload or ESD damage. Typical quiescent current is only 80µA while operating and less than 1µA in shutdown. The driver and receiver feature three-state outputs with the driver outputs maintaining high impedance over the entire common mode range. Excessive power dissipation caused by bus contention or faults is prevented by a thermal shutdown circuit which forces the driver outputs into a high impedance state. The receiver has a fail-safe feature which guarantees a high output state when the inputs are left open.
  • Thermal shutdown protection
  • Power up/down glitch-free driver outputs permit live insertion or removal of transceiver
  • Driver maintains high impedance in three-state or with power OFF
  • Up to 32 transceivers on the bus
  • Pin-compatible with the LTC485
  • 1µA Quiescent current in shutdown mode
