Sukhbinder Posted March 2, 2006 Report Share Posted March 2, 2006 H there all of u! i need a circuit to perform a power on reset for digital ics. i need something that is small ans simple using only simple discreet components like resistors,capacitors and transistor. no special ics please. the ic is a better choice but procuring it for me is a bit tricky here in INDIA. so i would really appreciate if u guys provided me with a simple solution.thanks ;) Quote Link to comment Share on other sites More sharing options...
Staigen Posted March 2, 2006 Report Share Posted March 2, 2006 Hi there SukhbinderCmos or TTL?//Staigen Quote Link to comment Share on other sites More sharing options...
Sukhbinder Posted March 2, 2006 Author Report Share Posted March 2, 2006 Any thing that will work for both. I know about the working voltages for both TTL and CMOS but i still have to decide which type to use depending on their availabilitythanx ;) Quote Link to comment Share on other sites More sharing options...
Staigen Posted March 2, 2006 Report Share Posted March 2, 2006 HiA simple one, use schmitt-triggersTTL: use a 7414 or similar, connect a 10K resistor to + and a electrolytic cap to groundCMOS 4000 series: use a schmitt and a resistor to + and a cap to - or a resistor to - and a cap to +//Staigen Quote Link to comment Share on other sites More sharing options...
