Frequently Asked Questions
What supply voltage range does the HC type support?
The HC types operate from 2V to 6V supply voltage.
When do these flip-flops change state?
They change state on the negative-going transition of the clock pulse.
What happens if both Set and Reset go High simultaneously?
Output states are unpredictable if both S and R go High after both being low.
What is the operating temperature range?
The operating temperature range is -55°C to 125°C.
