CD74HC4060 Datasheet, PDF (2/10 Pages) Texas Instruments – High Speed CMOS Logic 14-Stage Binary Counter with Oscillator

CD74HC4060, CD74HCT4060
Description
TTL switching levels.
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
