74HC4060; 74HCT4060 14-stage binary ripple counter with oscillator
Rev. 5 — 8 May 2020 Product data sheet 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. 2. Features and benefits
