My problem is that I would like to use 'faster' reset, with reset
delay time up to 100ms. By datasheet 2114 needs min 10 ms. For
Microchip circuit time delay is 140 ms min, up to 0.5 sec(!) max.
Any idea/recomendation? Again, I am little bit sceptical to use rC
circuit reset in professional stand-alone application.
