Note: 1) Guaranteed by design.
2) Duty = 0.5, VBS >=7V
3) Guaranteed by design. Pulse widths below the specified values, may be ignored. Output will either follow the input signal or will ignore it.
No false output state is guaranteed when minimum input width is smaller than tin
4) Guaranteed by design
