NOTE 4: These limits apply only to applications that use more than two ’HC163 devices cascaded together.
If the ’HC163 devices are used as a single unit, or only two cascaded together, then the maximum clock
frequency that the devices can use is not limited because of the glitch. In these situations, the devices can be
operated at the maximum specifications.
A glitch can appear on RCO of a single ’HC163 device, depending on the relationship of ENT to CLK. Any
application that uses RCO to drive any input, except an ENT of another cascaded ’HC163 device, must take
this into consideration.
