DESCRIPTION
The 74LV4060 is a low-voltage Si-gate CMOS device and is pin and
function compatible with the 74HC/HCT4060.
The 74LV4060 is a 14-stage ripple-carry counter/divider and
oscillator 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 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 the other input conditions.

NOTES:
1. CPD is used to determine the dynamic power
dissipation (PD in mW)
PD = CPD x VCC2 x fi + S (CL x VCC2 x fo) where:
fi = input frequency in MHz; CL = output load capacity in pF;
fo = output frequency in MHz; VCC = supply voltage in V;
S (CL x VCC2 x fo) = sum of the outputs.
2. The condition is V1 = GND to VCC
3. For formula on dynamic power dissipation, see the
following pages.
