LTC2870-Slide2

The LTC2870 is a robust, pin-configurable multi-protocol transceiver supporting RS232, RS485, and RS422 protocols. From the circuit diagram, it can be seen that the device can be configured as two RS232 single-ended transceivers or one RS485 differential transceiver on shared I/O lines. The LTC2870 operates from 3V to 5.5V at up to 20Mbps in RS485 mode or 500kbps in RS232 mode. The protocol is pin-selectable, which in turn automatically selects the correct termination resistors. In the RS485 mode, users can also pin-select half- or full-duplex. A 1.7V to 5.5V logic supply pin ensures logic voltage compatibility with the user’s system microcontroller or UART. The LTC2870 also has very high ±26kV ESD HBM protection on the transceiver pins that ensures it can survive even the most rugged environments. Finally, the LTC2870 is available in a 28-pin 4mm x 5mm QFN package, as well as a 28-pin TSSOP leaded package.
