Iron - We investigate the chip K561IE10A.

                 K561IE10A


   Mikruha K561IE10A - two binary irreversible (probably 
asynchronous) counter the dumping and the ability to account 
bipolar pulses. In fact, everything is much easier ...


    Everyone (regardless of) the counter - is:

    4 (standard 1-2-4-8) output.

   3 inputs: R - reset. CN - from negative (negative pulse). CP 
- through positive (positive pulse). 


   I reset the highest priority: R = 1 - output the number 0, 
the inputs of the CN and CP do not influence. When R = 0 is 
possible by increasing order. 

   Account for the positive impulses: to
CN 0 (authorization bill), and the CP itself
pulses, the decay of which (the change: 1 - 0)
is the increment of the counter. When CN = 1 for
CP does not respond to input, store the previous number.

   For an account of negative impulses: to
CP 1 (enabled the account), and the CN itself
impulses along the front of which (ie, as sometimes 
misinterpret: the decay of the pulse of negative polarity, 
change: 0 -> 1) occurs increment the counter. When CP = 0 on 
the input of CN is responds, keeps the old number.


   Interestingly, when closed together the inputs of the CN and 
CP (synchronous - in-phase) counter did not react to impulses - 
not considered as a inversion (synchronous antiphase) considered

positive impulses (from the fall: 1 - 0).
But I do not remember with any input on what sound an alarm via 
an inverter (or is it not important?). Perhaps the delay 
through K561TL1 to enter the same (561) series is not 
important. Perhaps in the formal technical data it is 
stipulated, but I am inclined assume synchronous switch inputs 
incorrect and does not intend to do so. 

   I wonder what the technical features
mikruhi denotes the letter A (the title)?

   According to some reports, the maximum clock frequency of 
0.3 MHz. But do not trust this source, I at least because does 
not specify under which the supply voltage mikruha may receive 
such impulsy.Ved within 3 - 15 V performance is clearly not

same!



   The graph pictured on the noodle, but according to the logic 
mikruhi.
