ACPL-K54L-560E

Optoisolators are devices used in electronic circuits designed to transfer electrical signals from one circuit to another in an isolated fashion. By using an optical isolator, electrical isolation is achieved between input and output circuits, enabling them to operate at different potentials. They are essential components in many electronic circuits, especially those found in medical systems, automotive, aerospace, military, industrial process control and telecommunications applications. The ACPL-K54L-560E is an optoisolator belonging to the family of Transistor, Photovoltaic Output optoisolators.

The ACPL-K54L-560E is a 4-channel, 10-bit high-speed photovoltaic transducer optoisolator module. It consists of four bidirectional channels and a separate ground pin. The channels within the module are isolated from each other, allowing input and output signals to operate at different voltage levels.

The ACPL-K54L-560E is designed to be used in circuits and applications requiring differential input and output levels, such as pulse-width modulation (PWM) output systems. It can be used in a wide variety of applications, including DC-to-DC power conversion, current control, and voltage regulation. The ACPL-K54L-560E can also be used for data transmission, for example, passing data between controllers and a variety of motor encoder and decoder systems. It has an operating temperature range of -40°C to 85°C and is housed in a 5-pin PDIP package.

The basic operating principle of the ACPL-K54L-560E is based on the operation of a phototransistor. A transistor is a semiconductor device composed of three layers of semiconductor material with different properties. These three layers are the base, collector, and emitter. A photon of light is injected into the base of the transistor, causing a change in the current between the collector and emitter.

The ACPL-K54L-560E incorporates four photovoltaic chips in a single package. Each chip consists of two phototransistors separated by a light source. A light emitting diode (LED) is used to transmit a single light beam across the chip, and the two transistors are positioned opposite each other to detect the light beam. The light beam is modulated by the input signal, and the two photo-transistors are connected in series so that any changes in the light beam will cause changes in current flow from one transistor to the other.

The ACPL-K54L-560E is ideal for applications where high reliability and performance are required. It is highly reliable, with a minimum of 2 million hours of operation, and has a fast response time of 10µs. It is also very reliable in terms of its electrical isolation, as it provides up to 67dB of isolation between the input and output circuits. The ACPL-K54L-560E also has an input-to-output random transients specification of ±500V, making it suitable for high-voltage applications. The ACPL-K54L-560E is an excellent choice for a variety of applications requiring conversions between differential input and output levels.
