LTC2859CDD#PBF - RS485/RS422 Transceiver

The LTC2859CDD#PBF is a robust RS485/RS422 transceiver from Linear Technology, designed to provide reliable data communication in industrial, networking, and telecom applications. This integrated circuit is housed in a compact DFN-10 package, ensuring a small footprint that is ideal for space-constrained designs.

Key Features:

• Interface Type: The product supports RS485 and RS422 communication standards, providing versatile options for serial data transmission.
• Data Rate: It offers a high data rate of up to 20Mbps, facilitating fast and efficient data exchange.
• Integrated Protection: Enhanced with integrated electrostatic discharge (ESD) protection, the LTC2859CDD#PBF can withstand up to ±15kV, ensuring robustness against electrical transients.
• Supply Voltage: Operating from a single 3.3V supply, it is optimized for low-voltage applications while maintaining low power consumption.
• Extended Temperature Range: The device is designed to operate over an industrial temperature range of -40°C to 85°C, making it suitable for harsh environments.
• Duplex Configuration: It supports half-duplex communication, allowing bidirectional communication on a single pair of wires.
• Fail-Safe Receiver: The fail-safe receiver ensures a logic-high receiver output when the inputs are open or shorted, or when they are connected to a terminated transmission line with all drivers disabled.
• Power-Up/Down Glitch-Free: Driver outputs remain in a high impedance state during power-up or power-down, which prevents glitches on the bus.

Applications:

The LTC2859CDD#PBF is suitable for a range of applications, including but not limited to:

• Networked Industrial Control Systems
• Building Automation
• Factory Automation
• Telecommunication Systems

With its combination of high-speed communication, robust protection features, and reliability over a wide temperature range, the LTC2859CDD#PBF is an excellent choice for designers looking to implement RS485 or RS422 interfaces in their systems.
