The oscillator configuration allows design of either RC or crystal oscillator circuits. A Master Reset input is provided which resets the counter to the all-0’s state and disables the oscillator. A high level on the MR line acplishes the reset function. All counter stages are master-slave flip-flops. The state of the counter is advanced one step in binary order on the negative transition of φI (and φO). All inputs and outputs are buffered. Schmitt trigger action on the input-pulse-line permits unlimited rise and fall times. In order to achieve a symmetrical waveform in the oscillator section the HCT4060 input pulse switch points are the same as in the HC4060; only the MR input in the HCT4060 has TTL switching levels.
