LTC1482 Low Power RS485 Transceiver

LTC1482 Low Power RS485 Transceiver with Carrier Detect and Receiver Fail-Safe DESCRIPTIO The LTC®1482 is a low power RS485 compatible transceiver that offers an active low carrier detect output. The open-drain carrier detect pin allows several transceivers to share the same carrier detect line and can be used to detect the insertion or removal of a driven RS485/RS422 cable. Enhanced ESD protection allows the LTC1482 to withstand ±15kV (human body model), IEC-1000-4-2 level 4 (± 8kV) contact and.
