I found your suggestion good so i brought two MC14553 and two CD4543 ICs. I assembled the circuitry()given in the datasheet of MC14553 IC) on a breadboard, but I dont know why its not working. The 7 segment is showing only 8 or when i give it a clock, it sometimes shows a bogus 9 but no counting.
(I could not find MC14543 IC in market, but they said that the CD4543 also is same as MC14543)
Since it's working a little bit, that's a sign you've done most everything right.
Besides the clock input, there are several pins which must each be brought hi or low depending on what operation you wish.
These pins are:
clock enable
latch enable
BCD out
reset
To count pulses you must pull clock enable low. It enables the internal counters.
To see the changing count: You must (1) disable the latch, and (2) enable BCD out. As I recall you can operate it this way indefinitely.
Activate the reset pin to bring all counters back to zero.
If you only want to see the updated count at periodic intervals (example, frequency counter), then you (1) enable latch, (2) enable BCD out, (3) static display now shows previous count, (4) counters accumulate invisibly for one second, (5) disable latch, (6) disable BCD out, (7) activate reset, (8) return to step 1. There is a timing circuit that accomplishes this once each second. It uses several gates and capacitors.
As you can see you need to apply signals hi and low at the proper times, to get everything working in sync.
It's an established popular IC. Helpful schematics and explanations can be found at websites, such as these links:
