Additional Details:

The SP202EET/TR utilizes charge pump circuitry to generate the necessary ±10V RS-232 voltage levels from the single 5V supply. It typically requires external capacitors for charge pump operation. The TR suffix usually indicates that the part is supplied in tape and reel packaging for automated assembly.
