The TLP2391(E) is an optoisolator device of the logic output family. It consists of a gallium arsenide infrared source LED optically coupled to a light-sensitive silicon transistor that has been incorporated into a 6-pin dual-in-line package. 

This device isolates logic input levels from the output circuit, making it suitable for a variety of applications, including data communication systems, process controls, test and measurement systems, laboratory infrastructures, and many more. Furthermore, it is available in a range of medium to long-term temperature ranges.

The basic working principle behind the TLP2391(E) optoisolator is the creation of an electrical barrier between its input and output circuits. This barrier is formed using a specially designed LED which is then coupled, through an optical link, to a phototransistor. This is the fundamental structure of most optoisolator devices.

The optical link is responsible for achieving the electrical isolation between the two circuits. As light from the LED passes through the link, it is picked up by the phototransistor which then switches its output state accordingly. This switching mechanism is controlled by the input signal driving the LED. 

In terms of performance, the TLP2391(E) offers high-gain, fast response times, and superior noise rejection. It also provides an excellent level of electrical isolation, and a wide range of input/output combinations. This makes it suitable for use in a variety of applications.

The TLP2391(E) is also designed to be mechanically robust. It is constructed with epoxy molding material that provides superior shock and vibration stress. This feature is important to ensure that it functions reliably in any environment.

In summary, the TLP2391(E) is an optoisolator of the logic output family. Its main function is to isolate logic input levels from the output circuit. It possesses a range of features such as high-gain, fast response times, superior noise rejection, and reliable mechanical construction. This makes it suitable for a variety of applications, including data communication systems, process controls, test and measurement systems, and laboratory infrastructures.
