Working Principles

The ICL3241IBZ operates by converting logic-level signals to RS-232 voltage levels using internal charge pumps. It provides a single driver and receiver channel for bidirectional communication. The device is powered by a supply voltage in the range of 3.0V to 5.5V. Logic-level signals are applied to the transmitter input, which are then converted to RS-232 voltage levels and transmitted through the driver output. On the receiving end, RS-232 signals are received through the receiver input and converted back to logic-level signals.
