studying the datasheet of the ic's

i manage to find out and study the function on how n why to use the ic's in the circuit, well...the ic used are 4060 n 4093..from here, i know that the 4093 ic is an ic schmitt trigger, whereby this ic is important to shape the wave to send input to the ic 4060...the ic 4060 is the 14 ripple stage counter and oscillator ic, it is used to set time for the electronic sleep inducer...it is important to have this two ic's, due to the the 4093 ic is turning the sin wave to square wave, and the 4060 ic is to interpret the data, to receive the waves and change it into the signals needed...
