Frequently Asked Questions
What specific signal quality benefit do I get from the Schmitt trigger inputs?
They convert slowly changing input signals into sharply defined, jitter-free output signals and provide hysteresis.
How high a voltage can this chip safely tolerate at the inputs?
The inputs are inherently tolerant to voltages up to 7V, making it suitable for 5V, 3V, and 2.5V systems.
If I leave certain inverter gates unused, what is required for proper operation?
Unused inputs must be held either HIGH or LOW; they may not float.
Can this component be used in critical life support medical devices?
No, its use is not authorized for life support systems without the express written approval of Fairchild Semiconductor Corporation.
