Optoisolators - Logic Output

The ACPL-M21L-560E is a logic output optocoupler component that is ideal for a variety of applications such as industrial, commercial, and consumer control systems. It has a 5V logic output, which is also TTL compatible. It has a high common-mode transient immunity of > 30 kV/us and a low propagation delay of <500 ns. It has a wide operating temperature range of -55 °C to +125 °C. Additionally, it is housed in a Dip 8 package with lead-free and RoHS compliant terminals.

The ACPL-M21L-560E utilizes an optocoupler to provide electrical isolation between two circuits. An optocoupler is a device that couples an electrical signal from one side to another side, while keeping them electrically isolated. An optocoupler usually consists of a phototransistor and an infrared LED. The LED projects light onto the phototransistor which activates it, producing a signal. In the ACPL-M21L-560E, the LED is driven by a 5V logic output, and the phototransistor produces a 5V logic output. The output of the optocoupler isolates the input from the output circuit, eliminating the need for a transformer.

The ACPL-M21L-560E is ideal for a variety of isolation applications due to its high noise immunity, robustness, and high speed performance. The optocoupler can be used to isolate control circuits from supply variations and grounding problems. It can also be used to protect micro-controllers from over-voltage or electrical transients, or to couple two circuits that need to be operating at different levels of electrical volatility. In addition, the device eliminates ground loops, which can cause electromagnetic interference and other problems when two circuits need to be connected.

The ACPL-M21L-560E is designed to provide a secure connection between input and output, while still protecting electronics from potential damage due to electrical transients. With its high noise immunity, low propagation delay, and low power consumption, the ACPL-M21L-560E is an ideal optocoupler for any logic output application.
