1. General description

The 74HC4060; 74HCT4060 is a 14-stage ripple-carry counter/divider and oscillator with three

oscillator terminals (RS, RTC and CTC), ten buffered parallel 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. In this case, keep the oscillator pins (RTC and CTC) floating. The counter advances

on the HIGH-to-LOW transition of RS. A HIGH level on MR clears all counter stages and forces all

outputs LOW, independent of the other input conditions. Inputs include clamp diodes. This enables

the use of current limiting resistors to interface inputs to voltages in excess of VCC.
