General description
The 74HC4060; 74HCT4060 are high-speed Si-gate CMOS device and is pin compatible
with the HEF4060.
The 74HC4060; 74HCT4060 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 the counter (Q3 to Q9 and Q11 to Q13 = LOW), independent of
other input conditions. In the HCT version, the MR input is TTL compatible, but the RS
input has CMOS input switching levels and can be driven by a TTL output by using a
pull-up resistor to VCC.
