Frequently Asked Questions

Q: What is the difference between TLP521-2GB and TLP521-4GB optocouplers?

A: The TLP521-2GB is a dual-channel optocoupler IC, meaning it contains two isolated input/output channels in a single DIP package. The TLP521-4GB is a quad-channel version with four isolated channels. Both are part of the same TLP521 family and share similar electrical characteristics, but the 4GB variant offers more channels for more complex circuit designs.

Q: Are these TLP521 ICs compatible with Arduino and Raspberry Pi projects?

A: Yes! The TLP521-2GB and TLP521-4GB DIP optocouplers are widely used in microcontroller-based projects including Arduino and Raspberry Pi. They are excellent for isolating microcontroller GPIO pins from higher-voltage circuits such as relay modules, motor drivers, and industrial sensors.

Q: How many pieces are included in this lot?

A: This listing includes 10 pieces per lot. The pack may include a combination of TLP521-2GB and TLP521-4GB units — perfect for stocking up on essential optocoupler components for multiple projects.
