Working Principles

The ICL3222ECAZ operates based on the principles of the RS-232 protocol. It uses voltage levels to represent binary data, where positive voltages indicate logic 0 and negative voltages indicate logic 1. The IC incorporates internal circuitry to handle the conversion between RS-232 voltage levels and CMOS/TTL logic levels.

When transmitting data, the IC converts the CMOS/TTL logic level signals into RS-232 voltage levels and sends them through the appropriate transmitter channel. On the receiving end, the IC receives RS-232 voltage levels and converts them back into CMOS/TTL logic levels for further processing.
