CD74HC4060ME4 [Texas Instruments]

The 'HC4060 and 'HCT4060 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 resets the counter to all-0's state and disables the oscillator. All counter stages are master-slave flip-flops. The state advances one step in binary order on the negative transition of φI (and φO). All inputs and outputs are buffered with Schmitt trigger action on the input-pulse line.
