Product Summary

The LTC1690CS8#PBF is a Differential Driver and Receiver Pair. 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. The LTC1690CS8#PBF is fully specified over the commercial and industrial temperature ranges. The LTC1690CS8#PBF is available in 8-Pin SO, MSOP and PDIP packages. The applications of the LTC1690CS8#PBF include Battery-Powered RS485/RS422 Applications, Low Power RS485/RS422 Transceiver, Level Translator and Line Repeater.
