Optoisolators are devices that provide electrical isolation between two circuits while still allowing a signal to pass one way. This helps protect circuits from voltage spikes or other electrical disturbances. The TLP185 Optoisolator is an example of a transistor, photovoltaic output optoisolator. It is designed to provide galvanic isolation and electrical noise suppression between two digital logic circuits.

The TLP185 Optoisolator utilizes a photovoltaic cell and a single NPN transistor output to achieve tremendous noise immunity. Its low-voltage digital input is optically coupled to the photovoltaic cell. When the input voltage exceeds the threshold, the resulting current activates the transistor. When the input voltage is below the threshold, the transistor is held in the “off” state.

The TLP185 can be used for general purpose digital logic level isolation in a wide variety of applications such as computers, detector control systems, industrial control systems and data communication systems. This optoisolator is designed for use in logic-level applications using digital input devices such as clocked logic gates, ICs and MOSFETs. It can also be used to isolate noisy analog logic in single-ended or push/pull control applications.

The TLP185 has a wide range of features that make it an attractive option for digital logic level isolation. It has excellent electrical characteristics, with a maximum propagation time of 200ns and a minimum threshold voltage of 0.8V. Its maximum collector-emitter saturation voltage is 0.6V, with a breakdown voltage rating of 40V. The optoisolator also has excellent noise immunity, with a minimum insulation resistance of 100MΩ at 500V AC for 60 seconds.

The TLP185 is well-suited for use in a variety of applications. In computer systems, the optoisolator can be used to provide isolation between microprocessor buses, such as the ISA or EISA bus. In detector control systems, the TLP185 can be used to provide a logic level signal to a receiver, such as a detector controller. In industrial control systems, the optoisolator can be used to provide output control signals to a system controller. In data communication systems, the optoisolator can be used to protect data communications links from external electrical noise.

The TLP185 is an effective solution for digital logic level isolation with excellent electrical characteristics and noise immunity. It is well-suited for use in numerous applications, and can provide a simple way to protect digital logic signals from external noise and interference. The optoisolator can also be used to provide galvanic isolation between two circuits, allowing them to interact without allowing electrical signals to pass back and forth.
