is there any one who knows what the 7497 TTL chip is? i
checked several data books but got no answer. its function
seems to be a kind of frequency multiplier which has a
pulse input and a 6-bit data input, its output's freqency
will be proportional to that data: Fout=Fin*data/64.
thanks in advance.
