CD4060 is composed of an oscillator and 14-bit binary serial counter bits. The structure of the oscillator can be an RC or crystal oscillator circuit. When CR is high, the counter is cleared and the oscillator is invalid. All counter bits are master-slave flip-flops. The CD4000 series include CD4060BM and CD4060BC. CD4000 counts in binary at the falling edge of CP1 (and CP0). Use Schmitt triggers on the clock pulse line to limit the clock rise and fall time.
