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
e
1, the CLK1 input is
selected and when SEL
e
0, the CLK0 input is selected.
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.
