Product Overview

The LTC2854CDD#PBF is a low power half-duplex 20Mbps RS485/RS422 Transceiver with integrated switchable termination operating on 3.3V supplies. The receiver includes a logic-selectable 120R termination, one-eighth unit load supporting up to 256 nodes per bus (C-, I-Grade) and a fail-safe 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 LTC2854 to withstand ±25kV (human body model) and the LTC2855 to withstand ±15kV on the transceiver interface pins without latch up or damage.
  • Integrated, logic-selectable 120R termination resistor
  • 3.3V Supply voltage
  • 20Mbps Maximum data rate
  • No damage or latch-up up to ±25kV HBM
  • High input impedance supports 256 nodes (C, I-grade)
  • Operation up to 125°C (H-grade)
  • Guaranteed fail-safe receiver operation over the entire common mode range
  • Current limited drivers and thermal shutdown
  • Delayed micro power shutdown (5µA maximum, C-, I-Grade)
  • Power up/down glitch-free driver outputs
  • Low operating current (370µA typical in receive mode)
  • Compatible with TIA/EIA-485-A specifications
