Product Summary

The LTC1484CS8#TR is a low power RS485 compatible transceiver. In receiver mode, it offers a fail-safe feature which 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. The applications of the LTC1484CS8#TR include Battery-Powered RS485/RS422 Applications, Low Power RS485/RS422 Transceiver, Level Translator.
