Optoisolators, also known as optocouplers or photocouplers, are integrated circuits that use light-emitting diodes (LEDs) to control an electrical signal/circuit. The HCPL-263A-300E is an optoisolator in the logic output category, which includes optoisolators with open-collector outputs. Logic output isolators are typically used in low power input isolation applications and provide 2500Vrms minimum isolation voltage. These devices are used to isolate two circuits that must be electrically isolated from one another; they provide a reliable isolation method that does not require any communication cables.

The HCPL-263A-300E includes an LED and phototransistor, which are isolated from one another by an optical barrier. The LED is coupled with a current limiting resistor connected to the input. When the input is at the logic level “ON”, the LED is turned ON and produces light. The light falls on the phototransistor’s base which causes a very small current to be drawn from the output. In the logic level “OFF”, the LED is off and no current is drawn from the output.

The operating voltage range of the HCPL-263A-300E is from 3.0V to 80V. It has an output voltage range from -0.6V to Vce(SAT) and it can support a maximum Ice of 10mA. The collector to emitter saturation voltage is typ. 0.85V at 10mA. It has an operational temperature range from -55°C to 125°C with an insulation voltage between 3000Vrms and 5000Vrms. Finally, it features an optical Isolation between the input and output of 2500V.

Due to its low power input and logic output features, the HCPL-263A-300E is popularly used in automated control systems and instrumentation, such as PLCs (Programmable Logic Controllers), PAC (Programmable Automation Controllers), I/O systems, and industrial systems. The HCPL-263A-300E is also used in data transmission isolation applications where various levels and noise resistance is required.

In addition to achieving data transmission isolation, optoisolators are also useful for switching applications due to their high voltage rating and fast response time. This makes them a great choice for numerous applications such as automotive systems, factory automation, AC to DC converters, and medical systems. Furthermore, due to their high insulation voltage rating, they are often used in smart grids and other power management systems.

The HCPL-263A-300E is a reliable optoisolator in the logic output category, with a wide range of applications in a variety of electrical systems. With its broad operating voltage, high isolation voltage rating, and lowpower input requirements, the HCPL-263A-300E is an ideal choice for automated control systems and industrial systems demanding high speed data and noise isolation.
