The MR34519MP8A is an opto-coupler from Matsushita (Panasonic). It is an integrated circuit designed for various applications in the electronics and communications industry as a circuit board indicator, array light bar, bar graph, and other LED systems.

An opto-coupler is a circuit component that uses a pair of light-emitting diodes (LEDs) to transfer electrical signals between two devices. It isolates the output of one device from the input of another, providing an effective interface between them. This enables them to communicate without engaging in a direct electrical connection, preventing noise, electrical spikes, or power disruptions from affecting the performance of the system.

The MR34519MP8A consists of 8 LEDs. The LEDs are arranged in a dual-phase configuration – 4 LEDs in series and the remaining 4 LEDs in parallel. Each LED has an operating current of 20mA, a forward voltage of 2.2V and a viewing angle of 160º. The LEDs are connected to two pins, with the active pin being VCC (2.2V for the LED forward voltage) and the other side being GND.

The main purpose of the MR34519MP8A is to indicate the status of a circuit or device. This can be achieved by connecting it to various types of logic circuits or microcontrollers. For example, it can be used as a circuit board indicator, flashing a pattern of LEDs to indicate certain conditions. It can also be used as an array light bar, to provide visual indication of the system\'s performance in terms of the current value, the peak value, and the average value. Finally, it can be attached to bar graphs, providing a visual display of data such as temperature or sound level.

The MR34519MP8A includes features that make it well suited for a wide range of applications. It has a wide operating voltage range of 2.7V to 13.2V, low current consumption of 5mA, low operating temperature of -45°C to +65°C, and a high shock durability of up to 8G.

In conclusion, the MR34519MP8A is a versatile circuit board indicator, array light bar, bar graph, and other LED systems. It is designed for a wide range of applications, from simply indicating a circuit status to providing a visual display of data. The MR34519MP8A can be used for a variety of purposes due to its wide operating voltage range, low current consumption, low operating temperature, and high shock durability.
