MC74HC4060AFELG

14−Stage Binary Ripple Counter With OscillatorHigh–Performance Silicon–Gate CMOS
The MC74HC4060A is identical in pinout to the standard CMOS MC14060B.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTLoutputs. This device consists of 14 master−slave flip−flops and an oscillator with a frequency that is controlled either by a crystal or by an RC circuit connected externally.
The output of each flip−flop feeds the next and the frequency at each output is half of that of the preceding one.
The state of the counter advances on the negative−going edge of the Osc In.
The active−high Reset is asynchronous and disables the oscillator to allow very low power consumption during stand−byoperation.State changes of the Q outputs do not occur simultaneously because of internal ripple delays.
Therefore, decoded output signals are subject to decoding spikes and may have to be gated with Osc Out 2 of the HC4060A.
