LT1785IN8 Description

Short technical summary and product information.

The LT1785IN8 is a half-duplex and full-duplex differential bus transceiver designed for RS485 and RS422 applications. It features on-chip protection from overvoltage faults on the data transmission lines, with protection up to ±60V.

 

Key electrical specifications include a maximum data rate of 0.25 Mbps and a supply current of 5.5mA. The device offers robust ESD protection up to ±15kV (air discharge) and ±4kV (contact discharge) per IEC-1000-4-2 standards. It is designed to operate reliably up to 125°C, with specific variants available for commercial (0°C to 70°C) and industrial (-40°C to 125°C) temperature ranges.

 

This transceiver supports up to 128 nodes and is pin-compatible with LTC485 and LTC491. It includes features like short-circuit protection on all outputs and thermal shutdown protection. The LT1785IN8 is available in N-8 and SO-8 packages, suitable for surface mount applications.

 

Applications for the LT1785IN8 include industrial control systems, data networks, CAN bus applications, and HVAC controls. Its fault tolerance and high input impedance make it a reliable choice for demanding communication environments.
