      freinds

      i have a design for the low frequency counter without the help of the complex processors or the costly ics

      but few question are there without which i cant give it the reality
      1) what is the maximum frequency obtained by LM555 as the astable multivibrator
      2) What is the minimum time pulse of the LM555 as the monostable multivibrator
      3) what is the maximum frequency of the signal that can be converted into square wave using the schmitt trigger using IC 741


      Thank you
      sanjay

        555 max frequency is around 500khz (refer datasheet) use 324 instead of 741 to generate square wave sanjay soni wrote: freinds i
