Figure 46 shows the characteristics of the input filters
while receiving narrow ON and OFF pulses. If input
signal pulse duration, PW IN , is less than input filter time,
t FLTIN ; the output pulse, PW OUT , is zero. The input signal
is rejected by input filter. Once the input signal pulse
duration, PW IN , exceeds input filter time, t FLTIN , the
output pulse durations, PW OUT , matches the input pulse
durations, PW IN . FAN73892 input filter time, t FLTIN, is
about 250 ns for the high- and low-side outputs.

3.2. Short-Pulsed Input Noise Rejection Method
The input filter circuitry provides protection against
short-pulsed input signals ( HINx , LINx , and EN) on the
input signal lines by applied noise signal.
If the input signal duration is less than input filter time
(t FLTIN ), the output does not change states.
Example A and B of the Figure 45 show the input and
output waveforms with short-pulsed noise spikes with a
duration less than input filter time; the output does not
change states.
