Introducing the LTC1347CN from Linear Technology

The LTC1347CN is a robust and versatile RS485/RS422 transceiver chip designed by Linear Technology, a company renowned for its high-performance analog integrated circuits. This transceiver is engineered to provide reliable data communication in industrial and commercial applications where long-distance data transmission is required. The LTC1347CN is ideal for networked control systems, factory automation, and other demanding environments.

Key Features of the LTC1347CN

• High-Speed Operation: The LTC1347CN supports data rates up to 5Mbps, making it suitable for high-speed data communication tasks.
• Differential Bus Transceiver: It operates as a differential bus transceiver, which means it can transmit and receive data over a balanced line that significantly reduces susceptibility to electromagnetic interference (EMI).
• Fail-Safe Receiver: The device ensures a fail-safe receiver output of a high state if the inputs are open or shorted, or if the inputs are connected to a terminated transmission line with all drivers disabled.
• Thermal Shutdown Protection: Built-in thermal shutdown protection ensures that the device operates within safe temperature ranges, preventing damage from overheating.
• Low Power Consumption: The LTC1347CN features a low quiescent current, which makes it an energy-efficient choice for battery-powered applications.
• Driver and Receiver Enable Functions: Separate enable pins for the driver and receiver provide additional flexibility and control, allowing the transceiver to be placed in a low-power shutdown mode when not in use.

Robust Design and Compatibility

The LTC1347CN is housed in a sturdy 14-pin PDIP (Plastic Dual In-line Package), ensuring it can withstand the rigors of tough industrial environments. Its pinout is industry-standard, which allows for easy integration into existing designs without the need for significant board rework.

With its superior ESD (Electrostatic Discharge) protection, the LTC1347CN ensures resilience against common electrical hazards, making it a reliable choice for critical applications. Its extended common-mode range enables it to cope with ground loop voltages, which is a common challenge in complex installations.

Whether you're upgrading an existing system or designing a new one, the LTC1347CN from Linear Technology offers the performance, reliability, and quality that professionals demand.
