The SP211ECT-TR is a single RS-232 transceiver manufactured by Sipex Corporation (now part of Exar). This device is designed to provide a simple and efficient interface between a microcontroller or other digital logic device and an RS-232 serial communication port.

Applications

• Embedded systems serial communication
• Modem interfaces
• Data acquisition equipment
• Diagnostic ports
• Level translation between digital logic and RS-232

Features

• Single RS-232 transceiver
• Low power consumption
• High data rates
• Integrated charge pump for RS-232 voltage levels
• Short-circuit protection
• EIA/TIA-232 compatible

Benefits

• Simplified RS-232 interface design
• Reduced board space
• Reliable serial communication
• Protection against electrical faults
• Easy integration into existing systems

Additional Details

The SP211ECT-TR operates from a single 5V power supply and generates the necessary RS-232 voltage levels using an internal charge pump. It supports data rates up to a specified maximum (check datasheet). The device is protected against short circuits on the RS-232 side, enhancing system reliability. Sipex (Exar) offers datasheets detailing electrical characteristics, timing diagrams, and package dimensions. The "-TR" suffix generally indicates that the part is packaged on tape and reel for automated assembly.

This part is suitable for applications requiring a single channel RS-232 interface, such as connecting a microcontroller to a serial port for debugging, configuration, or data transfer. Due to its low power and compact size, it's suitable for portable and battery-powered devices. Often used for legacy systems, it provides voltage level shifting.
