PC123Y23FP9F

Optoisolators, also known as optocouplers, are electronic devices that provide electrical or optical isolation between two circuits. In addition to blocking high voltage, optoisolators protect from signal noise and interference from one circuit to another. Most commonly, optoisolators are built using a light emitting diode (LED), or other light source, and a photodetector or phototransistor. The PC123Y23FP9F belongs to an optoisolator family known as Transistor, Photovoltaic Output.

The PC123Y23FP9F employs a 6-pin dual inline package (DIP) with pins configured along two rows. In normal operation, LED side emits infrared light, which is then received by the photodetector side. The collector of the phototransistor is connected to the output terminal, while the emitter of the LED is connected to ground. The device also includes a buffer between the signal pin and the transistor base. The buffer serves to level and ac-couple the external signal to the detector, thus ensuring interfacing of the device with a wide array of logic families.

The PC123Y23FP9F is particularly well suited for applications such as digital logic level conversion and signal isolation. Its wide bandwidth makes it particularly capable of high-speed digital applications, such as serial bus communication signals or audio/video signals. In addition, due to its increased impedance characteristic, the device provides superior isolation and noise immunity. Furthermore, it is capable of sustaining a large number of logic signal transitions without symptom degradation.

The PC123Y23FP9F provides the necessary isolation and low operating currents to reduce the risk of electrical shock when interfacing two circuits. Its features including supply voltage of 5 Volts, LED Current Consumption of 5 mA, and Collector Sink Current of 8 mA, make it an ideal selection for applications utilizing signal and logic interface. The optoisolator is capable of a wide range of voltage input and output levels, making it a useful device for signal demultiplexing, level shifting, and isolation.

The PC123Y23FP9F is a reliable and reliable optoisolator, and its price point provides a great value. The device has been proven to be a reliable and efficient way of providing electrical isolation across two circuits. It is ideal for a variety of applications, including digital logic level conversion and signal isolation for data communication and other applications.
