Frequently Asked Questions
What synchronizes the counter's output rate?
The output pulse rate is determined by signals applied to the Select (S0±S5) inputs.
How can I reset the entire counter asynchronously?
Use the asynchronous Master Reset input (MR), which must be Active HIGH to prevent counting and reset the device.
What voltage range should the module operate at?
The operating supply voltage (VCC) range is specified between 4.5V minimum and 5.5V maximum.
Are these components suitable for life support equipment?
No, National Semiconductor products are not authorized for use as critical components in life support devices without express written approval.
