14-stage ripple-carry binary
counter/divider and oscillator
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.
