Optoisolators - Logic Output are a form of signal transmission where the digital signal is isolated from the source of control. This isolation allows for two parts of the system, the circuit providing the signal and the circuit receiving the signal, to communicate with each other without any electrical connection. The HCPL-2212-360E is an optoisolator device, designed to be placed between a digital logic output and an optically-coupled device, providing galvanic isolation up to PC board level. Using LED and photodetector-opto-coupler technology, this application field and working principle is designed to make sure that stray capacitance, crosstalk, and other disturbances from the external environment do not interfere with the signal.

The HCPL-2212-360E is designed to provide two separate channels of optoisolation between the input logic and the logic output. Channel 1 is designed to accept either open-collector types of logic inputs, such as TTL, or totem-pole outputs such as CMOS. Channel 2 accepts only CMOS inputs, and both channels provide logic-level outputs up to 10V. This allows for higher speed operation than more traditional optoisolators, and also helps to keep the emitted noise low.

The HCPL-2212-360E optoisolator provides its signal isolation by using two separate components. The first component is an LED which is activated by an electrical signal. When the LED is activated, the light from the LED is transmitted through an optical window towards a photodetector. The photodetector converts the light signal into an electrical signal which is then transmitted to the logic output. This signal isolation protects both the transmitted signal and the logic output from interference due to external electrical noise.

The application fields of the HCPL-2212-360E optoisolator are numerous as they can be used for a variety of applications. These include, but are not limited to, data transmission, low voltage analog signals, and even in medical equipment. The device can also be used to interface between different voltage levels and logic families in the same system, helping to ensure that the different voltages do not interfere with one another.

The HCPL-2212-360E is a greatly advanced version of traditional optoisolators. Unlike traditional optoisolators, the HCPL-2212-360E does not require the use of an external voltage source, and is thus more energy efficient. Its CMOS input capabilities allow for faster signal transmission speeds and lower noise generation. With these features, and its low price tag, the HCPL-2212-360E has proven to be an effective optoisolator for those looking for an efficient and budget friendly solution to their signal transmission needs.
