TLP785F(D4GLT7,F

The TLP785F(D4GLT7,F optoisolator is an economical way to provide optimal isolation and data transfer between various digital systems. It is part of the Transistor, Photovoltaic Output optoisolators family that provides basic input-to-output isolation for digital, line interface, or logic signals. It offers a maximum collector current of 20 mA, a maximum direct output current of 100 mA, and a minimum turn-on time of 350 ns.

The optoisolator works by using a photovoltaic device that switches a transistor on and off when a light beam is projected onto it. The device is enclosed in a clear epoxy housing, which has a slit on the end that allows the light beam to reach the photovoltaic device. The device can be used to send serial data or logic signals between circuits and systems that would otherwise be isolated from each other. It is recommended for use where input-output isolation and/or power contamination is desired.

The TLP785F(D4GLT7,F\'s application fields include:

• Isolating digital systems from each other.
• Providing logic signals and serial data transfer between systems.
• Preventing power contamination or noise between systems.

The working principle of a standard Transistor, Photovoltaic Output optoisolator is as follows: electrical or digital signals (i.e., logic, data, voltage, current) are input on the signal input side of the isolator. The signal is then converted into a light beam by a gallium arsenide LED. The light beam passes through the epoxy slit, activating a photovoltaic device. This device then switches a transistor on or off according to the amount of emitted light. The transistor is then used as an amplifier to turn the signal into a larger, output version (hence the name "amplifier-type" optoisolator). The amplified signal is then output on the signal output side, isolating the signal from the input side.

The TLP785F(D4GLT7,F optoisolator is an efficient and cost-effective device designed to provide optimal isolation and data transfer between systems. It is suitable for use in a wide range of applications, including isolating digital systems, providing logic signals and serial data transfer, and preventing power contamination or noise between systems.

The optoisolator operates on a simple yet highly effective operating principle, allowing it to provide the necessary input-output isolation. It is an efficient and economical device that can be easily integrated into most systems, making it an ideal choice for isolating digital systems and eliminating power contamination or noise between systems.
