Same, Sebosfato!

Thanks for all the info   :)

What we should know about logic IC's
« Reply #68 on: March 05, 2011, 20:37:54 pm »
You're welcome bro.


I would like to explain some differences between TTL Ic's (those witch stan used) and CMOS IC's..


TTL IC's are very fast, they can work up to 35MHZ, being them normally composed of bipolar transistors this explain the high speed but at the same time the big hungry for power to work. Also the old ic's had open collector configuration, witch allows the used to select the proper pull up resistor for the application.


CMOS IC's (4000, 4500) series are very economic (energy consumption) cause they are based on mosfet, they don't need pull up resistors... But they are very slow compared to TTL, up to 30 times slower.


High speed CMOS (74HCXX) this have a good speed and are very economic (energy consumption), this is what i'm going to use from now.


H stands for high frequency


I'm going to use the following IC's in my new prototype,


74HCT7046 PLL 5v (This IC have the lock in build in, you just need to add a capacitor and led for it to detect the difference in phases you accept to tell you if is locked in...


Than high speed nor gates SN74HC02N 5V


Than for the resonant feedback circuit


LM741 or CA3140  or LF411 cause i already have here...


ANd i will use the ir4427 as the driver...


I will probably try using bipolar transistors for the drive stage but as worked already previously i'm going to use the irfp460 before.




Close to every IC you need to put a 47uF and 100nF capacitors to filter noize..


I still don't know what counters i will use... I still have some sn74ls90n but i'm not sure if they are not burned...


Anyway i think that i will try to find some from the 74hct series...

Sebo,


nice waveforms, we've all seen them, however........


pudding time, as in proof..........   any more gas?
