The 74HC/HCT4060 are high-speed Si-gate CMOS devices and are pin compatible with “4060” of the “4000B” series.
The 74HC/HCT4060 are 14-stage ripple-carry counter/dividers and oscillators with three oscillator terminals (RS, RTC and CTC), ten buffered outputs (Q3 to Q9 and Q11 to Q13) and an overriding asynchronous master reset (MR).
The oscillator configuration allows design of either RC or crystal oscillator circuits.
The oscillator may be replaced by an external clock signal at input RS.
