The LT1280CN is a robust dual transceiver designed by Linear Technology, now part of Analog Devices, that integrates two RS232 drivers and two receivers into a single package. This device is engineered to function as a reliable interface between data terminal equipment (DTE) and data communication equipment (DCE), providing seamless data transmission for a wide array of applications.

Key Features:

• Integrated Charge Pump Circuitry: The LT1280CN includes an onboard charge pump that generates the necessary RS232 voltage levels (+10V and -10V) from a single 5V supply, eliminating the need for additional power supplies.
• Low Power Consumption: Designed for power-sensitive applications, it operates with a low supply current, making it an ideal choice for portable and battery-operated equipment.
• High Data Rates: Capable of supporting data rates up to 120kbps, the LT1280CN is suitable for high-speed data communication.
• Driver Output Shutdown: It features a shutdown mode that reduces power consumption by disabling the driver outputs when not in use.
• ESD Protection: The transceiver's inputs and outputs are protected against electrostatic discharge events, ensuring reliability and longevity in harsh environments.

Applications:

The LT1280CN is versatile and can be used in various communication interfaces, including:

• Portable Computing Devices
• Modems
• Printers and Scanners
• Industrial Control Systems
• Data Acquisition Systems

Package and Quality:

The device is offered in a 16-pin narrow DIP package, ensuring easy integration into existing designs. It is also characterized for operation from 0°C to 70°C, making it suitable for commercial-grade applications. With Linear Technology's reputation for high-quality components, the LT1280CN stands as a reliable choice for designers looking to implement RS232 communications with minimal external components and robust protection features.
