HI for all

can somone give me a clear schemtatic about this counter and its oscillator (555, RC ,....).

thanx
 

Re: counter 8 bit 74HC590

Hi,

Everything you need is in the datasheet **broken link removed**

Not aware it has an oscillator ? What are you trying to do ?
 

Re: counter 8 bit 74HC590

hi Mr wp100

"The counter and storage register have
separate positive edge triggered clock (CPC and CPR) inputs"(from data sheet)

this means that we should use an oscillator

////////////////////////////////////////////////////
about your quest:
I want to count from 0 to 127 during 0.1 sec

thank u
 

Re: counter 8 bit 74HC590

Hi,

Its difficult to give a definative answer as you only refer to the 74hc590.

It all depends on what your input source is ? are the voltages compatible, what are you doing with the resultant output ?

As you can see from the datasheet the chip needs not just a clock pulse but other control lines as well, what will be creating them ?

Perhaps using a pic micro might be a simpler way that will also allow you to process the pulses further.

thank you very much Mr Wp100

I will see this docs , and give u the result
