Input Transients

The MIC841/2 is inherently immune to very short negative-

going “glitches.” Very brief transients may exceed the V

IN(LO)

threshold without tripping the output.

As shown in Figure 3, the narrower the transient, the deeper

the threshold overdrive that will be ignored by the MIC841/2.

The graph represents the typical allowable transient duration

for a given amount of threshold overdrive that will not gener-

ate an output.
