Frequently Asked Questions
How do PRE or CLR inputs affect the outputs?
A low level at the preset (PRE) or clear (CLR) inputs sets or resets the outputs, regardless of other input levels.
What is the maximum continuous output current allowed?
The continuous output current (IO CC) rating is ±25 mA.
How do I configure this device to act as a toggle flip-flop?
You can make it function as a toggle flip-flop by tying both the J and K inputs high.
What is the total storage temperature range for this chip?
The storage temperature range (T stg) is from -65°C to 150°C.
