74HC/HCT4060 is a 14-stage binary ripple counter with oscillator
The Philips 74HC/HCT4060 is a high-speed Si-gate CMOS device featuring a 14-stage ripple-carry counter/divider and an on-chip oscillator. It includes ten buffered outputs (Q3 to Q8 and Q11 to Q13) and an overriding asynchronous master reset (MR). The device is pin compatible with the '4060' of the '4000B' series and complies with JEDEC standard no. 7A.

Yes, in the HCT version, the MR input is TTL compatible, while the RS input has CMOS input switching levels.
The maximum clock frequency is 88 MHz for the HCT version and 87 MHz for the HC version.
To avoid start-up problems, the resistor R1 should be set to 1 kΩ.
The capacitor C1 must be larger than 50 pF to maintain agreement with the typical oscillation formula.
