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.

A HIGH level on MR resets the counter (O3 to O9 and

O11 to O13 = LOW), independent of other input conditions.

Schmitt-trigger action in the clock input makes the circuit

highly tolerant to slower clock rise and fall times.
