LTC2870CFE#PBF

Drivers, Receivers, Transceivers Overview

The LTC2870CFE#PBF is a robust pin-configurable multiprotocol transceiver supporting RS232, RS485, and RS422 protocols. It operates on a single 3V to 5.5V supply voltage with a logic interface range of 1.7V to 5.5V. The device integrates two RS232 single-ended transceivers or one RS485 differential transceiver on shared I/O lines. It features an integrated DC/DC boost converter for RS232 levels, eliminating the need for multiple supplies. Pin-controlled termination resistors allow automatic selection between 120Ω for RS485 and 5kΩ for RS232. The component supports up to 256 RS485 nodes and includes half-duplex switching capabilities.
