Product Overview

The LTC2857IDD-1#PBF is a low power RS485/RS422 Transceiver operating on 5V supplies at maximum data rates of 20Mbps for low EMI. The receiver has a one-eighth unit load, supporting up to 256 nodes per bus and a failsafe feature that guarantees a high output state under conditions of floating or shorted inputs. The driver 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 thermal shutdown.
  • 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
  • Power up/down glitch-free driver outputs
  • Compatible with TIA/EIA-485-A specifications
