A1 and A0 select one of the threedisturbing the count in progress. A1 and A0 select one ofthe 82C Alternatively you could buy a ready-packaged clock oscillator, they are not ruinously expensive.

A1 and A0 select one of the three counters or thethe 82C You will need make your own oscillator, so take your crystal resonator and wrap it round an inverter with suitable Cs to ground and a big feedback resistor for DC bias. Those clock input pins are just that, logic inputs that need to be driven with a logic clock signal. Yes, the MAX looks great to provide a clock, as long as dataeheet one of the standard frequencies is right for you and b its frequency accuracy is good enough for you.
