PC3H4A

The PC3H4A optoisolator is an optically isolated, three channel transistor and photovoltaic output device used for signal isolation, combining logic, data transmission, and control. The device utilizes a light source to transmit a signal across an isolating barrier, providing a completely isolated interface between two circuits.

Optoisolators are devices with a light-emitting diode (LED) or infrared source (IR LED) as input and a phototransistor as the output. This provides electrical isolation between the input and output, since the light signal is only able to pass across the pair of isolated compoents. This makes optoisolators ideal for applications where a digital input needs to be isolated from the rest of a circuit.

The PC3H4A consists of three individual channels of optoisolator technology, each with two input pins, an output pin, and a ground pin. The input pins allow for two-channel logic operations, making it ideal for control line signals which require optical isolation from other parts of a circuit. The output pin is used to transmit the isolated signal, and the ground pin ensures the output remains at zero volts.

The PC3H4A optoisolator works by utilizing a Light Emitting Diode (LED) and a light sensitive transistor (LST). The LED produces a small amount of light when an electrical current is applied to it, and this light passes through an isolating barrier between the two components. The LST is placed on the opposite side of this barrier, and it is sensitive to the light produced by the LED. When the LST is exposed to the light, it turns on, allowing current to flow through the output pin.

The PC3H4A optoisolator is an extremely useful device for a wide range of applications, especially in the areas of communications and computing. It can be used to isolate control signals from other parts of a circuit, as well as for signal transmission and logic operations. The device’s three channels of optoisolator technology make it ideal for combining logic and data transmission operations into a single device, providing a highly reliable and cost-effective solution for many circuits.

The PC3H4A optoisolator is a must-have for any circuit which requires electrical isolation to protect sensitive components and reduce the risk of voltage and current transients. It is an extremely reliable and cost-effective optoisolator which provides the perfect solution for data transmission, logic operations, and signal isolation.
