linear DESIGN FEATURES LTJournal-V21N2-03-df-LTC2870_71-Steven_Tanghe service manual
The LTC2870 and LTC2871 are multiprotocol transceivers designed to simplify applications using both RS485 and RS232 standards. The LTC2870 combines two RS232 transceivers with one RS485 transceiver on shared I/O pins, while the LTC2871 offers separate pinouts for all three transceivers allowing simultaneous operation.
