Expert FAQ
Q: What is the undefined voltage zone?
A: Voltages between 0.4V and 4.5V cannot guarantee definite on/off states. Avoid this range during normal operation.
Q: What devices can this TTL module control?
A: It controls logic circuits, digital displays, opto-isolators, and other low-power 5V DC devices.
Q: Why is a minimum load current required?
A: A 0.15 mA current ensures proper transistor operation and reliable output detection.
Q: Can I use it in high-vibration environments?
A: Yes, but the open module requires additional protection such as an enclosure in harsh conditions.
