Working Principles

The ICL3222CB operates based on the RS-232 protocol, which defines the electrical characteristics of serial communication between devices. It uses a combination of voltage levels and timing to transmit and receive data.

When transmitting data, the IC converts the logic-level signals from the device into RS-232 compliant voltage levels. These voltage levels are then transmitted through the appropriate channel to the receiving device. On the receiving end, the IC converts the RS-232 voltage levels back into logic-level signals that can be understood by the receiving device.
