MIC841/2

Input Transients

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

going “glitches.” Very brief transients may exceed the VIN(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.
