Working Principles

The ICL3222ECP operates based on the RS-232 standard, which defines the electrical characteristics and signaling for serial communication. It uses voltage levels to represent binary data, where positive voltages indicate logic 0 and negative voltages indicate logic 1.

The IC incorporates transmitter and receiver circuits that convert digital signals into RS-232 compliant voltage levels and vice versa. The transmitter section converts logic-level signals from the device's microcontroller or UART into RS-232 voltage levels suitable for long-distance transmission. The receiver section performs the reverse operation, converting RS-232 signals back into logic-level signals for further processing by the device.
