Working Principles

The ICL3238EIV-T operates based on the RS-232 protocol, which uses voltage levels to represent binary data. It consists of a transmitter and a receiver section. The transmitter converts digital logic signals into RS-232 voltage levels, while the receiver performs the reverse conversion.

When transmitting data, the transmitter section receives digital logic signals from a microcontroller or digital circuitry and converts them into RS-232 voltage levels suitable for transmission over long distances. On the receiving end, the receiver section detects the RS-232 voltage levels and converts them back into digital logic signals.

The IC incorporates features like automatic power-down and enhanced ESD protection to ensure reliable and efficient data transfer.
