The HCPL-2601#300 is a type of optoisolator belonging to the Logic Output family. It features high common-mode immunity, high physical galvanic isolation, and provides stable output characteristics regardless of changes in optical coupling and ambient temperature.

The HCPL-2601#300 is an isolated digital interface circuit specifically designed to transfer digital signals and power between two or more circuits that are separated by medium to high levels of Galvanic isolation. Its input and output signals remain completely isolated from each other, allowing the HCPL-2601#300 to be used in safety critical applications, such as medical device interface, in which the output signal must not be affected by input noise generated by other circuits.

The selection of an optoisolator requires knowledge of the specific application requirements. A typical application of the HCPL-2601#300 would involve optically coupling TTL and/or logic compatible signals between circuits with up to 1500 Vrms (peak AC deflection) isolation.

The HCPL-2601#300 consists of an InGaAs light emitting diode (LED) optically coupled to an integrated photo-detector, which provides an inverted output. The HCPL-2601#300 has a high common-mode isolation, making it suitable for transferring data and power between circuits with different ground potentials. The high common-mode isolation also makes the device immune to electrical noise, such as transients or interference, which are more likely to occur in electrically noisy and highly sensitive environments.

When correctly used, the HCPL-2601#300 provides high reliability and stable output characteristics over a broad temperature range and even during large changes in optical coupling or ambient temperature. Moreover, its high CMRR (Common-Mode Rejection Ratio) eliminates the need for expensive signal conditioning systems.

The HCPL-2601#300 optoisolator features a high current rating of up to 100 mA per channel. This makes the device suitable for use in low-current applications, such as the transmission of low-level TTL and/or logic compatible signals, including clock signals up to 100 MHz.

The HCPL-2601#300 is designed for easy assembly and board mounting. Its high speed performance and exceptional noise immunity make the device an ideal choice for both industrial and telecom applications. The HCPL-2601#300 is certified and compliant with safety standards for electrical isolation and medical applications, such as IEC 60601-1.
