Product Overview

The LT1785CN8#PBF is a half-/full-duplex Differential Bus Transceiver for RS485 and RS422 applications which feature on-chip protection from overvoltage faults on the data transmission lines. Receiver input and driver output pins can withstand voltage faults up to ±60V with respect to ground with no damage to the device. Faults may occur while the transceiver is active, shut down or powered off. Data rates to 250kbaud on networks of up to 128 nodes are supported. Controlled slew rates on the driver outputs control EMI emissions and improve data transmission integrity on improperly terminated lines. Drivers are specified to operate with inexpensive cables as low as 72R characteristic impedance. The LT1785A device has "fail-safe" receiver inputs to guarantee a receiver output high for shorted, open or inactive data lines. On-chip ESD protection eliminates need for external protection devices.
  • Protected from overvoltage line faults to ±60V
  • Pin compatible with LTC485 and LTC491
  • High input impedance supports up to 128 nodes
  • Controlled slew rates for EMI emissions control
  • Guaranteed high receiver output state for floating, shorted or inactive inputs
  • Outputs assume a high impedance when off or powered down
  • Drives low cost, low impedance cables
  • Short-circuit protection on all outputs
  • Thermal shutdown protection
  • Guaranteed operation to 125°C
