Working Principles

The SP3222EUEA-L/TR is an RS-232 transceiver that operates by converting the voltage levels between RS-232 and TTL/CMOS logic. It uses internal charge pumps to generate the necessary voltage levels required for RS-232 communication. The transceiver receives RS-232 signals, converts them to TTL/CMOS levels, and transmits them to the connected device. Similarly, it receives TTL/CMOS signals, converts them to RS-232 levels, and transmits them over the RS-232 interface.
