CD74HCT4060MG4 [Texas Instruments]

The ’HC4060 and ’HCT4060 are 14-stage binary counters with an onboard oscillator. 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 permitting unlimited rise and fall times. Features include wide operating temperature range (-55°C to 125°C), balanced propagation delay and transition times, and significant power reduction compared to LSTTL. HC types operate from 2V to 6V with high noise immunity, while HCT types operate from 4.5V to 5.5V with direct LSTTL input compatibility.
