Product Overview

The LTC2859IDD#PBF is a low power RS485/422 Transceiver operating on 5V supplies. The receiver includes a logic-selectable 120R termination, one-eighth unit load supporting up to 256 nodes per bus and a fail-safe feature that guarantees a high output state under conditions of floating or shorted inputs. The driver features a logic-selectable low-EMI 250kbps operating mode and maintains high output impedance over the entire common mode range when disabled or when the supply is removed. Excessive power dissipation caused by bus contention or a fault is prevented by current limiting all outputs and by a thermal shutdown.
  • Integrated, logic-selectable 120R termination resistor
  • No damage or latch-up up to ESD - ±15kV HBM
  • Guaranteed failsafe receiver operation over the entire common mode range
  • Current limited drivers and thermal shutdown
  • Delayed micropower shutdown
  • Power up/down glitch-free driver outputs
  • Low operating current
  • Meets all TIA/EIA-485-A specifications
