Frequently Asked Questions
What function does the CLEAR input perform?
When held low, the Q output is forced into a low logic level, regardless of other inputs.
What is the typical maximum operating frequency?
The device typically operates at up to 80 MHz when Vcc is 4.5V.
What are the recommended supply voltage ranges for operation?
The specified operating voltage range (Vcc) is between 4.5 V and 5.5 V.
Are there limits on data input voltages?
Inputs can accommodate voltages from 0 V to 5.5 V, matching ground up to the supply voltage.
