Optoisolators are a class of semiconductor devices which contain a light-emitting diode (LED) and an integrated photodetector optically coupled within the same package. The LED component emits light which is detected by the photodetector in order to create electrical isolation between two circuits - providing exceptional noise immunity and safety protection. Optoisolators provide protection from voltage transients and electrical noise, including transients exceeding the power-supply voltage rating, and noise pulses with peak amplitudes greater than the supply voltage. They are also used to interface signals between different types of logic busses.

One example of an optoisolator device is the HCPL-2212#300. This device provides exceptional reliability and performance, and is suitable for a range of applications such as telecommunications, industrial, medical, and automotive. It is also RoHS-compliant and uses an optically-coupled LED within the package to provide LED-to-detector isolation of up to 3750Vrms. It is also compact in size, with dimensions of 7.62mm x 4.45mm x 2.20mm.

The HCPL-2212#300, which falls under the logic output optoisolator category, has two pins: an anode and a cathode. The LED anode is the output pin, and is used to output a logic level signal upon the correct application of an input signal. The LED cathode is the input pin, and is used to receive a logic level signal that will then be converted to an output signal from the LED anode.

An important aspect of the HCPL-2212#300 is that it is designed to provide exceptional noise immunity. It features high common-mode transient immunity, with a typical value of over 80kV/us. This is due to the electrical isolation provided by the optically-coupled LED, which guards against temporary voltage surges or large noise pulses. In addition, the device has a high operating temperature range and storage temperature range, with a maximum rating of 105°C and -55°C to 130°C respectively.

In terms of electrical performance, the HCPL-2212#300 has a minimum LED current of 6mA, a maximum LED current of 20mA, and a typical DC forward current gain of 5000. It also has a minimum frequency response of 10kHz, a maximum frequency response of 1MHz, and a typical delay time of 18ns. In addition, it operates from a wide range of powers, including 4.5V to 16V DC for single output, and 2.7V to 7V for dual output.

The HCPL-2212#300 is an excellent choice for applications that require electrical isolation and noise immunity. Its exceptional features make it suitable for a variety of applications including telecommunications, industrial, medical, and automotive. Its high operating temperature range and storage temperature range make it a reliable device for long lasting performance. Its wide range of power input also make it a great choice for applications that require flexibility. Overall, the HCPL-2212#300 is an excellent choice for applications that require isolated output signals with exceptional reliability and performance.
