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.
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
Schmitt-trigger action in the clock input makes the circuit
highly tolerant to slower clock rise and fall times.

Timing component limitations
The oscillator frequency is mainly determined by
RtCt, provided Rt << R2 and R2C2 << RtCt. The function
of R2 is to minimize the influence of the forward voltage
across the input protection diodes on the frequency. The
stray capacitance C2 should be kept as small as possible.
In consideration of accuracy, Ct must be larger than the
inherent stray capacitance. Rt must be larger than the
LOCMOS ‘ON’ resistance in series with it, which typically
is 500 Ω at VDD = 5 V, 300 Ω at VDD = 10 V and 200 Ω at
VDD = 15 V.
The recommended values for these components to
maintain agreement with the typical oscillation formula are:
Ct ≥ 100 pF, up to any practical value,
10 kΩ ≤ Rt ≤ 1 MΩ.
Typical crystal oscillator circuit
In Fig.5, R2 is the power limiting resistor. For starting and
maintaining oscillation a minimum transconductance is
necessary.
