The LTC485ACN8 is a versatile and robust low power differential bus transceiver designed by Linear Technology, now part of Analog Devices, to facilitate communication on RS485 and RS422 networks. This integrated circuit is specifically engineered to operate in extended industrial temperature ranges and is housed in an 8-pin PDIP (Plastic Dual In-line Package), making it suitable for through-hole mounting on printed circuit boards.

Key Features

• Low Power Operation: The LTC485ACN8 is optimized for low power consumption, drawing only 175μA of supply current when unloaded or fully loaded with the driver disabled.
• Wide Supply Voltage Range: It operates from a single 5V supply, making it compatible with a variety of digital systems and simplifying power supply design.
• High Speed: Capable of data rates up to 2.5Mbps, this transceiver is suitable for high-speed data communication in industrial, control, and networking applications.
• Thermal Shutdown Protection: The device includes thermal shutdown protection that disables the driver outputs when a fault condition causes excessive power dissipation, enhancing system reliability.
• Failsafe Receiver: The LTC485ACN8 ensures a failsafe receiver output in the absence of input signals, which is critical for maintaining data integrity during fault conditions.
• Pin-Compatible Upgrades: This transceiver is designed to be pin-compatible with the industry-standard SN75176, allowing for easy upgrades in existing designs.

Applications

The LTC485ACN8 is ideal for a range of applications that require reliable data transmission over long distances and in noisy environments. It is commonly used in:

• Industrial Control Systems
• Networked Devices (e.g., sensors, actuators)
• Building Automation
• Telecommunications Equipment
• Data Acquisition Systems

Technical Specifications
