1. General description

The HEF4060B is a 14-stage ripple-carry counter/divider and oscillator with three oscillator

terminals (RS, REXT and CEXT), 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 (REXT and CEXT) 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 VDD.
