Optoisolators, or optical couplers, are components that use light for electrical isolation between two circuits. The HCPL-0721-060E is one such isolated component, and it is part of the Logic Output range of optoisolators.

The HCPL-0721-060E features a single inputthat is optically coupled to an open collector output. It is designed to provide effective galvanic isolation between a logic input and output up to 6000 Vrms. This optoisolator provides high reliability and electromagnetic noise (EMI) immunity, making it an ideal choice for simple isolated input or output applications.

The HCPL-0761-060E typically finds application in switching and logic control and is suitable for converting the logic I/O used in various applications such as industrial and test equipment, programmable logic controllers (PLCs), or any other type of programmable circuit. Driven by a valid logic signal, the input LED is illuminated, which causes the output phototransistor to conduct. In most logic applications, this allows the output to be connected directly to a microcontroller input.

The working principle of this component is based on the use of photons from an input infrared light-emitting diode (LED) to illuminate a phototransistor on the opposite side of the isolation barrier. The reverse current in the phototransistor switches on when the input LED is activated, which then provides an isolated output signal from the component. This working principle can be used for data communications, power supply regulation, voltage regulation, sensor isolation, motor speed control, relay contact isolation, and much more.

The HCPL-0721-060E is available in various packages such as DIP-4, SOP-4, and SMD-4 options. It is rated for 3500 Vrms of isolation at 25°C and has a wide temperature range of -40°C to +85°C. It also features high common mode transient immunity, with a wide operating supply voltage range of 5V to 30V, making it ideal for a variety of industrial-grade applications.

In summary, the HCPL-0721-060E is an optoisolator that belongs to the Logic Output range of optoisolators. It is designed to provide effective galvanic isolation between a logic input and output up to 6000 Vrms, making it suitable for switching and logic control applications. The working principle is based on the use of photons from an input LED to illuminate a phototransistor on the other side of the isolation barrier, which then provides an isolated output signal. The HCPL-0721-060E is available in various packages and has a wide temperature and operating supply voltage range, making it ideal for industrial-grade applications.
