The LTC2870 and LTC2871 are multi-protocol transceivers that combine RS485 and RS232 standards in a single device to simplify and shrink applications that use both standards. They support data rates as high as 20Mbps for the single RS485 transceiver and 500kbps for two RS232 transceivers.
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.
The device supports data rates as high as 20Mbps for the single RS485 transceiver.
The device supports data rates up to 50kbps for two RS232 transceivers.
The devices accept a wide range of input supply voltages from 3V to 5.5V.
