Functional Description
On the multiplexed clock device the SEL pin is used to
determine which CLKn input will have an active effect on
the outputs of the circuit When SEL
selected and when SEL
The non-selected CLKn input will not have any effect on the
logical output level of the circuit The output pins act as a
single entity and will follow the state of the CLK or
CLK1 CLK0 pins when either the multiplexed (’2526) or the
straight (’2525) clock distribution chip is selected
