LTC1483IN8#PBF - Differential Bus Transceiver from Linear Technology

The LTC1483IN8#PBF is a robust differential bus transceiver designed by Linear Technology, now part of Analog Devices, for high-speed bidirectional communication on multipoint bus transmission lines. It is specifically crafted to operate in environments with stringent requirements for data integrity and reliability. This product is ideal for long-distance communications and noisy industrial applications where a differential line driver and receiver are necessary.

Featuring a half-duplex interface, the LTC1483IN8#PBF is compatible with the RS485 and RS422 standards, ensuring seamless integration into a variety of communication systems. Its design is optimized for balanced data transmission and provides a high degree of noise immunity, making it suitable for complex electrical environments.

The device operates from a single 5V supply and features a low quiescent current of 220µA, which drops to a mere 10µA in shutdown mode. This power efficiency makes it an excellent choice for power-sensitive applications. The LTC1483IN8#PBF also boasts a driver output capability of up to ±60V and receiver input impedance of 96kΩ, providing robust protection against transients and enhancing system reliability.

Key features of the LTC1483IN8#PBF include:

• Half-Duplex RS485/RS422 Transceiver
• Single 5V Supply Operation
• Low Quiescent Current: 220µA
• Ultra-Low Shutdown Current: 10µA
• Driver Output Capability: ±60V
• Receiver Input Impedance: 96kΩ
• Thermal Shutdown Protection
• Pin-Compatible with the LTC485
• Available in Narrow 8-Lead PDIP Package

The LTC1483IN8#PBF also includes thermal shutdown protection to prevent damage from excessive power dissipation and over-temperature conditions. Its pin-compatible nature with the LTC485 offers designers a drop-in upgrade path for improved performance without the need for significant board redesigns.

Encased in a narrow 8-lead PDIP package, the LTC1483IN8#PBF is designed to withstand industrial temperature ranges from -40°C to 85°C. This robust construction, combined with its advanced features, makes it a reliable choice for industrial networks, control systems, and any application requiring a high-performance differential bus transceiver.
