The family TTL
The advantage of easily handle TTL family With it without extra precautions Ka used with integrated circuits Type of the CMOS .. In addition, it does not need More than 5 volts only ..
IC ics 1700
Chose here to focus on practice More in theory .. This will start in sequence from the integrated circuit
ICs7400 which contain Four gates of the NAND type, not ICs 7408, which contains four gates oftype AND
This is an integrated circuit of ICs 7400 More circuits of the TTL used .. Especially for general applications Which generally do not require frequency High .. more than 10 ns .. And the average amount consumed byapproximately 40 mW ..
Easy to check this circuit .. Whether they are installed in the department oroutside .. Just follow the table in the drawing ..
Integrated circuit ics 7402 .. Especially for general applications Which generally do not require frequency High .. more than 10 ns .. And the average amount consumed byapproximately 50 mW ..
.. meditate through the examination process Followers of the following table
Note: For the screening process used zero or one checker ..Special circuits of the TTL .. You can use the volt meter .. More Primary about 4.5 to 5 volt express one .. And zero to less than 2 volts.
