Working Principles

The ICL3222EIAZ-T operates based on the principles of RS-232 communication. It receives and transmits data using differential signaling, where logical levels are represented by voltage differences between two lines. The IC incorporates internal circuitry to convert these voltage differences into standard CMOS/TTL logic levels.

When receiving data, the IC detects the voltage difference between the receiver inputs (R1IN/R2IN) and converts it into a digital signal. This signal is then processed and made available at the respective receiver outputs (R1
