The LT1785HS8#PBF is a versatile and robust low power differential bus transceiver from Linear Technology, designed to meet the requirements for RS485 and RS422 communications. This transceiver is characterized by its low power consumption and extended industrial temperature range, making it an ideal choice for demanding applications in industrial, automotive, and telecommunications sectors.

Key Features

• Low Quiescent Current: The device operates with a very low supply current, typically 200µA, which is ideal for power-sensitive applications.
• Extended Temperature Range: With an operating temperature range of -40°C to 85°C, the LT1785HS8#PBF is suitable for use in harsh environments.
• High Data Rates: It supports data rates up to 2.5Mbps, allowing for fast data transmission in real-time applications.
• Driver and Receiver Enable: Separate enable pins for the driver and receiver provide additional flexibility and power saving opportunities by allowing each section of the transceiver to be independently disabled when not in use.
• Thermal Shutdown Protection: The device includes thermal shutdown protection that disables the driver outputs to prevent damage from excessive heat.
• Failsafe Receiver: The receiver has a failsafe feature that ensures a logic-high output if the inputs are open or shorted, or if they are connected to a terminated transmission line with no signal present.
• Robust ESD Protection: Enhanced ESD protection is built-in, withstanding ±15kV on the transceiver interface pins to protect against electrical transients.

Applications

The LT1785HS8#PBF is designed for bidirectional communication on balanced transmission lines and is suitable for a variety of applications, including:

• Industrial control systems
• Networked devices in building automation
• Automotive diagnostics and infotainment systems
• Professional audio and video equipment
• Telecommunication infrastructure
