Working Principles

The ICL3222IV operates based on the RS-232 protocol, which defines the electrical characteristics and signaling for serial communication. It uses a combination of voltage levels and timing to transmit and receive data between two devices.

When transmitting data, the ICL3222IV converts the logic-level signals from the transmitting device into RS-232 compliant voltage levels. These voltage levels are then transmitted over the RS-232 interface to the receiving device. On the receiving end, the ICL3222IV converts the RS-232 voltage levels back into logic-level signals that can be understood by the receiving device.
