The ACPL-217-700E is a single-channel, high-gain, low input current optocoupler in a compact 8-pin DIP package. This optocoupler uses a light-emitting diode (LED) and an integrated high-gain photodetector to provide electrical isolation between input and output circuits. It is designed for applications requiring high sensitivity and low input current drive.

Applications:

• Digital logic isolation
• Microprocessor system interface
• Pulse transformer replacement
• Current loop receiver
• Analog signal isolation

Features:

• High current transfer ratio (CTR)
• Low input current requirement
• High common-mode transient immunity
• Compact 8-pin DIP package
• Safety approvals: UL, CSA, IEC/EN/DIN EN 60747-5-5
• Operating temperature range: -40°C to +85°C
• High isolation voltage

Benefits:

• Provides electrical isolation for sensitive circuits
• Reduces ground loop noise
• Enables interfacing between circuits with different voltage levels
• Saves board space due to compact package
• Enhanced system reliability and safety
• Simplifies design with well-defined specifications

Additional Details:

The ACPL-217-700E features a high current transfer ratio, which minimizes the required input current to activate the output. This makes it suitable for interfacing with low-power microcontrollers and other low-current drive circuits. The high common-mode transient immunity ensures reliable operation in noisy environments, preventing spurious switching due to voltage transients. The safety approvals guarantee that the device meets stringent safety standards for electrical isolation. It is RoHS compliant.

The typical current transfer ratio is very high, allowing for low input currents. The collector-emitter breakdown voltage is high, which ensures safe operation even with relatively large power supply voltages. The device is packaged in an industry standard 8-pin DIP package for easy installation and soldering.
