The SP3232EBER-L is a powerful device, allowing communication between systems operating on different logic levels and protocols. This is a device which is highly reliable, due to its sleek, compact design and its ability to withstand environmental disturbances.

Working Principle

The SP3232EBER-L device works by converting TTL compatible logic input signals into RS-232 compatible output signals. It does this by using a driver circuit and a receiver circuit. The driver circuit consists of a buffer, level shifter, ECL125 and ECL100, and an output protection circuit. The buffer and level shifter convert the TTL logic signals into RS-232 output signals, while the ECL125 and ECL100 circuits ensure the output signal has the specified tolerance range. The output protection circuit prevents overloaded signal output.

The receiver circuit consists of a signal buffer, input protection circuit, and an open drain level shifter. The signal buffer receives the signal and the input protection circuit prevents the saturation of the signal. The open drain level shifter converts the RS-232 compatible signal into a TTL compatible signal. The device is equipped with an internal one-wire interface and uses a loopback mode for diagnostics, providing the system with improved signal accuracy and higher signal integrity. The device is compatible with a wide range of temperature ranges and is able to operate at up to 3.6V.
