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 an.
