6.15.2 Sample and Hold details

As described above, Output follows Input1 as long as Input 2 is 'High'. When Input 2 goes Low, the output
adopts the instantaneous value of Input 1 until Input 2 goes High again. When Input 2 goes high the output
jumps to the current value of Input 1 and tracks it until Input 2 goes low.
