Frequently Asked Questions
What input voltage range can I apply to the pins?
The input protection circuit allows voltages from 0V to 7V, regardless of the supply voltage.
Can this gate connect systems with different supply voltages (e.g., battery backup)?
Yes, it can interface 5V to 3V systems and two separate supply sources.
What is the device's typical high-speed switching time?
The typical rise time (t) at room temperature is 3.7ns.
If I leave an input pin unconnected, what must I do?
Unused inputs must be held either HIGH or LOW; they should not be allowed to float.
