7.1 Minimum Pulses
A typical 5-ns deglitch filter removes small input pulses introduced by ground bounce or switching transients. To change the output stage on OUTA or OUTB, one has to assert longer pulses than tPW(min), typically 10 ns, to guarantee an output state change. see Figure 7-1 and Figure 7-2 for detailed information of the operation of deglitch filter.
