Description

The Harris CD74HC4060 and CD74HCT4060 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.
