TRS3122ERGER Description

Short technical summary and product information.

The TRS3122ERGER from Texas Instruments is a highly integrated RS-232 transceiver featuring two drivers and two receivers. It supports a wide operating voltage range from 1.65V to 5.5V, making it compatible with various system voltages. The device boasts a data rate of 1Mbps and includes enhanced ESD protection on its input and output pins, rated up to ±15 kV IEC 61000-4-2 air-gap discharge.

 

This transceiver is designed for mixed-voltage operation with split supply pins and features a unique charge pump architecture that enables low voltage operation while maintaining compatibility with higher voltage supplies. It comes in a compact 24-VQFN (4x4) package suitable for surface mounting. The operating temperature range is -40°C to 85°C, ensuring performance in diverse environmental conditions. With a low shutdown supply current of 0.5 µA, it is also suitable for power-sensitive applications.

 

The TRS3122ERGER meets or exceeds the compatibility requirements of the RS-232 interface standard. Its integrated level-shifting functionality can eliminate the need for external components, simplifying board design. The device is suitable for applications requiring robust serial communication interfaces.
