Outputs a logical "1" at output y if x < S.
Outputs a logical "1" at output y if x > S.
Outputs a logical "1" at output y if x < S.
If x >= S + H, y returns to 0.
Outputs a logical "1" at output y if x > S.
If x <= S - H, y returns to 0.
x is limited to the upper limit value LU and the
lower limit value LL and is output at output y.
The binary signals MLU and MLL have the
value "1" if upper or lower limiting is active.
Sample and hold element.
y = x if SET = 1
