Product Overview

LTC2855 is a low power, 20Mbps RS485/RS422 transceiver operating on 3.3V supplies. The receiver includes a logic-selectable 120Ω termination, one-eighth unit load supporting up to 256 nodes per bus (C-, I-Grade), and a failsafe feature that guarantees a high output state under conditions of floating or shorted inputs. The driver maintains a 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. Enhanced ESD protection allows the LTC2855 to withstand ±15kV on the transceiver interface pins without latch up or damage.
  • Full duplex
  • Guaranteed failsafe receiver operation over the entire common mode range
  • Current limited drivers and thermal shutdown
  • Delayed micropower shutdown: 5µA maximum
  • Power up/down glitch-free driver outputs
  • Low operating current: 370µA typical in receive mode
  • Compatible with TIA/EIA-485-A specifications
  • 16-lead (narrow 0.150) plastic SSOP package
  • Temperature range from 0°C to 70°C
