Working Principles

The TRS3227CDBR operates based on the RS-232 protocol, which uses voltage levels to represent binary data. It incorporates transmitter and receiver circuits that convert digital signals into analog voltages and vice versa. The transmitter converts logic-level signals into RS-232 compliant voltage levels, while the receiver performs the reverse process.

When transmitting data, the IC converts the digital signal into a series of voltage pulses according to the RS-232 standard. On the receiving end, it detects these voltage pulses and converts them back into digital signals for further processing by the connected device.
