GENERAL DESCRIPTION
The 74HC, HCT4060 are high-speed Si-gate CMOS devices and are pin compatible with “4060” of the “4000B” series. They are specified in compliance with JEDEC standard no. 7A.
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. In this case keep the other oscillator pins (RTC and CTC) floating.
The counter advances on the negative-going transition of RS. A HIGH level on MR resets t.
