LTC2872 Overview
Key Features
- Pin-controlled integrated termination resistors allow for easy interface reconfiguration, eliminating external resistors and control relays
- Half-duplex switches allow four-wire and two-wire RS485 configurations
- Loopback mode steers the driver inputs to the receiver outputs for diagnostic self-test
- The RS485 receivers support up to 256 nodes per bus, and feature full failsafe operation for floating, shorted or terminated inputs
