The 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.
