Additional Details:

The ADM202AARNZ incorporates charge pump circuitry to generate the necessary ±10 V RS-232 voltage levels from a single +5 V supply. It also includes robust input protection circuitry that can withstand overvoltage conditions up to ±30 V. The transceiver is designed to operate over a wide temperature range and is available in a space-saving 16-lead narrow body SOIC package.

The driver outputs are short-circuit protected and can drive loads up to 3 kΩ. The receiver inputs have a high impedance, minimizing loading on the RS-232 bus. The ADM202AARNZ is a reliable and versatile RS-232 transceiver suitable for a wide range of applications.
