Description

The ’HC4060 and ’HCT4060 each consist of an oscillator

section and 14 ripple-carry binary counter stages. 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 accomplishes 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.
