To provide the best EMI robustness solution, a deglitch filter based on a non-resettable mono-stable has been

integrated. As described in Figure 6. Deglitch filter, to avoid parasitic spike in output signal when glitches occur in

input signals, the integrated internal buffer cleans the glitch effect.

The output activation and deactivation action times is defined by tPLH and tPHL when no glitch.
