Working Principles

The ICL3241IA operates based on the RS-232 protocol, which uses voltage levels to represent binary data. It consists of receiver and driver circuits for each channel. The receiver circuit converts incoming RS-232 signals into logic-level signals, while the driver circuit converts logic-level signals into RS-232 signals for transmission.

When data is received, the receiver circuit amplifies and filters the incoming signals to ensure accurate data recovery. On the other hand, the driver circuit generates RS-232 signals based on the logic-level input, providing the necessary voltage levels for transmission.
