LTC2804IGN-1#PBF - High-Speed Dual RS232 Transceiver with Integrated Charge Pump

The LTC2804IGN-1#PBF from Linear Technology is a robust, high-speed dual RS232 transceiver chip designed to meet the interface requirements for standard serial communication. This integrated circuit provides two receivers and two drivers and features an onboard charge pump circuit that generates the necessary RS232 voltage levels from a single 3.3V or 5V supply. This eliminates the need for multiple power supplies, saving space and reducing complexity in design.

Key Features:

• Integrated Charge Pump: Generates ±10V RS232 voltage levels from a single supply, which can range from 2.7V to 5.5V, making it versatile for various applications.
• High Data Rates: Capable of data rates up to 1Mbps, allowing for high-speed data communication.
• Low Power Consumption: The device features a low operating current, which is ideal for battery-powered and portable devices.
• Automatic Power-Down: When no RS232 cable is connected, the device automatically powers down, further conserving power.
• ESD Protection: Equipped with robust electrostatic discharge (ESD) protection, which exceeds ±15kV for both human body model and IEC1000-4-2 air discharge.

Applications:

The LTC2804IGN-1#PBF is suitable for a wide range of applications where RS232 communication is required. It is particularly well-suited for portable or battery-powered devices such as PDAs, laptops, and mobile communication equipment. Its small footprint and integrated functionality make it an excellent choice for space-constrained applications.

Package and Quality:

This product is offered in a 16-lead narrow SSOP package, providing a compact solution that is easy to integrate into system designs. The LTC2804IGN-1#PBF is also RoHS compliant and adheres to Linear Technology's commitment to high-quality and reliability standards, ensuring stable and continuous performance in various operating conditions.
