Short-Pulse / Noise Rejection
This device’s input filter provides protection against short-pulses (e.g., noise) on the input lines. If the duration of the input
signal is less than t
, the output will not change states. Example 1 of Figure 14 shows the input and output in the low state
FIL,IN
with positive noise spikes of durations less than t
; the output does not change states. Example 2 of Figure 19 shows the
FIL,IN
input and output in the high state with negative noise spikes of durations less than t
; the output does not change states.

Figure 14: Noise rejecting input filters
Figures 15 and 16 present lab data that illustrates the characteristics of the input filters while receiving ON and OFF pulses.
The input filter characteristic is shown in Figure 15; the left side illustrates the narrow pulse ON (short positive pulse)
characteristic while the left shows the narrow pulse OFF (short negative pulse) characteristic. The x-axis of Figure 20 shows
the duration of PW
, while the y-axis shows the resulting PW
duration. It can be seen that for a PW
duration less than

OUT
IN
t
, that the resulting PW
duration is zero (e.g., the filter rejects the input signal/noise). We also see that once the PW

OUT
IN
duration exceed t
, that the PW
durations mimic the PW
durations very well over this interval with the symmetry

improving as the duration increases. To ensure proper operation of the HVIC, it is suggested that the input pulse width for the
high-side inputs be ≥ 500 ns.
The difference between the PW
and PW
signals of both the narrow ON and narrow OFF cases is shown in Figure 16; the
OUT
IN
careful reader will note the scale of the y-axis. The x-axis of Figure 21 shows the duration of PW
, while the y-axis shows the
IN
resulting PW
–PW
duration. This data illustrates the performance and near symmetry of this input filter.
