HCPL-7723: Optoisolators - Logic Output are a type of optoelectronic devices that allow isolated communication between two circuits. This can provide protection to circuits from overvoltages and other disturbances. The HCPL-7723 is a optoisolator from the Logic Output family created by the Avago Technologies. It is a small-footprint optically coupled isolator with 1.5 kV/2 kV rms input-to-output isolation.

The HCPL-7723 is a single-channel device that includes an infrared LED as the input and an open collector logic output with photodetector. The input side includes an LED that is optically coupled to an open-collector photodetector and a signal-processing circuit on the output side. The signal-processing circuit includes a high-speed comparator that drives an open-collector output transistor. When the device is activated, the LED illuminates the photodetector, and the resulting voltage is compared with the reference voltage, resulting in an output logic signal indicating the result of the comparison.

The device has a wide range of applications, from low-speed to high-speed switching of digital signals. It can be used as an asynchronous switch to isolate pulse transformer circuits, providing secure isolation to digital circuits from potential transient disturbances. It is also used as an optical-speed counter/timer to generate pulse-width modulation (PWM) signals used in power supply circuits. It is also used for motherboard protection from damages due to power line transients, as well as for providing secure logic communication between two systems.

The HCPL-7723 has a wide operating voltage range from 4.5 to 25 V, and its low-power design and wide input-to-output isolation makes it suitable for use in portable applications. It also has a very low on-state resistance, making it ideal for light load applications. The open-collector design of the output allows it to be used as an input to TTL and CMOS devices.

The HCPL-7723 incorporates a number of features to ensure reliable long-term operation. It has an auto-restoration feature that helps the device recover from non-destroyed output faults. It is ESD-protected, so it can be reliably used in high-EMI environments. It also uses a state-of-the-art photo-muller construction to improve durability and reliability.

The HCPL-7723 is a versatile optically-isolated switching solution that can be used in a wide range of applications. Its high-speed signal processing, wide operating voltage range, and low power design make it ideal for portable and power supply applications. Its high input-to-output isolation and ESD protection make it suitable for use in high-EMI environments. Its low on-state resistance and open-collector design make it suitable for light load applications. The device is reliable and well-suited for a variety of digital logic switching applications.
