Product Overview

The LTC2870HUFD#PBF is a robust pin-configurable Multiprotocol Transceiver supports RS232, RS485 and RS422 protocols, operating on a single 3 to 5.5V supply. The LTC2870 can be configured as two RS232 single-ended transceivers or one RS485 differential transceiver on shared I/O lines. 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.
  • High ESD - ±26kV
  • Logic loopback mode
  • RS485 Receiver failsafe eliminates UART lock-up
  • Supports up to 256 RS485 nodes
  • Half-/full-duplex RS485 switching
