DESCRIPTION

The HEF4060B is a 14-stage ripple-carry binary counter/divider and oscillator with three oscillator terminals (RS, RTC and CTC), ten buffered outputs (O3 to O9 and O11 to O13) and an overriding asynchronous master reset input (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. The counter advances on the negative-going transition of RS. HIGH level on MR resets the counter (O3 to O9 and O11 to O13 = LOW), independent of other input conditions.
