Product Overview

The LTC1690CS8#PBF is a low power Receiver/Driver pair that is compatible with the requirements of RS485 and RS422. The receiver offers a fail-safe feature that guarantees a high receiver output state when the inputs are left open, shorted together or terminated with no signal present. No external components are required to ensure the high receiver output state. Separate driver output and receiver input pins allow full duplex operation. 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.
  • Guaranteed high receiver output state for floating, shorted/terminated inputs with no signal present
  • Drives low residential telephone wires
  • Power-up/down glitch-free driver outputs permit live insertion or removal of transceiver
  • Driver maintains high impedance with the power OFF
  • Up to 32 transceivers on the bus
  • Pin-compatible with the SN75179 and LTC490
