DESCRIPTION
The LTC®1690 is a low power receiver/driver pair that is compatible with the requirements of EIA485 and EIA422. 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.


FEATURES
■ No Damage or Latchup to ±15kV ESD (Human Body Model), IEC1000-4-2 Level 4 (±8kV) Contact and Level 3 (±8kV) Air Discharge
■ Guaranteed High Receiver Output State for Floating, Shorted or Terminated Inputs with No Signal Present
■ Drives Low Cost Residential Telephone Wires
■ ICC = 600µA Max with No Load
■ Single 5V Supply
■ –7V to 12V Common Mode Range Permits ±7V Ground Difference Between Devices on the Data Line
■ 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
■ Available in SO, MSOP and PDIP Packages


APPLICATIONS
■ Battery-Powered EIA485/EIA422 Applications
■ Low Power EIA485/EIA422 Transceiver
■ Level Translator
■ Line Repeater
