Optoisolators are devices which are used to isolate an input signal from a circuit while controlling an output signal. They are used to provide an electrical isolation barrier between the input and output, without letting any kind of energy flow between them. The TLP719(TP,F) optoisolator is designed for use in digital systems which require an input voltage and a digital output. This device uses a transistor to provide isolation between the signal source and the controlled circuit.

The TLP719(TP,F) optoisolator is suitable for digital circuit applications requiring low drive currents, an open collector output, and a hysteresis response. It contains a transistor optically coupled to a photosensitive device. The TLP719(TP,F) uses a transistor to provide an electrical isolation barrier between the input and output, while the photosensitive device detects and activates the output transistor.

The TLP719(TP,F) optoisolator is non-polarity and features a reverse blocking circuit. This means the input signal and the output circuit are isolated from each other, even when the output is in the ‘off’ state. The optoisolator provides a high level of input isolation, up to 2500V, ensuring that the input signal and the output circuit are electrically separated. In addition, the TLP719(TP,F) offers high speed operation up to 70MHz. It is also designed to provide immunity to electrical disturbances such as radiated EMI.

The TLP719(TP,F) optoisolator works by detecting the input signal and turning on the output transistor. When the input signal is applied to the photosensitive device, it emits a current pulse which is fed to the output side of the optoisolator. This current pulse is used to switch the output transistor on or off. The switching action of the transistor is used to control the output circuit. The output can be used to control the flow of current or the voltage in the output circuit, allowing the optoisolator to control the output of the circuit.

The TLP719(TP,F) optoisolator is a versatile device which is useful in a variety of digital circuit applications. It is particularly suited for applications which require an input voltage, an open collector output, and a hysteresis response. It is also ideal for applications which require electrical isolation and high speed operation. The optoisolator provides an efficient and reliable way to isolate an input signal from a circuit while allowing the output signal to be controlled.
