The ACPL-064L-000E is an optoisolator designed for universal digital logic applications. It features a built-in logic output stage with an open-collector, low-side switch that can sink up to 200 mA of AC or DC current. The ACPL-064L-000E consists of an infrared light emitting diode optically coupled to a silicon avalanche photodiode, and is designed to meet the isolation requirements of ANSI/ESD S1.1-1989 and ISO 60950.

The ACPL-064L-000E’s internal opto-coupler consists of two main components: a light-emitting diode (LED), and a photodiode connected in series with a Schottky coil and an open collector transistor. There is also a resistor connected in series with the LED. The LED is encased in a transparent plastic housing for protection.

The LED emits light for a brief time whenever a DC voltage is applied across it. This light is picked up by the photosensitive element, the photodiode, which is biased by a forward voltage. The photodiode generates a small current, which is then amplified and output from the open collector transistor. This transistor is then used to control the current in an external circuit.

The ACPL-064L-000E’s design offers a number of advantages over conventional opto-isolators. These include superior performance, improved noise and temperature tolerance, and improved signal integrity. Furthermore, the LED is designed to be extremely reliable, as it is encased in a hardened plastic housing. This eliminates the need for additional components and extends the device’s life span.

The ACPL-064L-000E is well-suited for a variety of digital logic applications, including data communications and bus/data switching. Its wide supply voltage range (2.2 to 5.5 V), low power dissipation, and fast switching time make it an ideal choice for these types of applications.

The ACPL-064L-000E is also ideal for automotive applications, where it is used to isolate signals, reduce signal interference, and provide accurate switching. The device is suitable for operating temperatures between -40°C and +85°C, and is resistant to electrostatic discharge (ESD).

In conclusion, the ACPL-064L-000E is an versatile optoisolator for digital logic applications. Its design provides improved performance, signal integrity, and reliability. It is suitable for automotive and other applications, thanks to its wide supply voltage range, low power dissipation, and fast switching time.
