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.
