Description
CD4047BMS consists of a gatable astable multivibrator with logic tech-
niques incorporated to permit positive or negative edge triggered
monostable multivibrator action with retriggering and external counting
options.
Inputs include +TRIGGER, -TRIGGER, ASTABLE, ASTABLE,
RETRIGGER, and EXTERNAL RESET. Buffered outputs are Q, Q, and
OSCILLATOR. In all modes of operation, an external capacitor must be
connected between C-Timing and RC-Common terminals, and an
external resistor must be connected between the R-Timing and RC-
Common terminals.
Astable operation is enabled by a high level on the ASTABLE input or a
low level on the ASTABLE input, or both. The period of the square wave
at the Q and Q Outputs in this mode of operation is a function of the
external components employed. “True” input pulses on the ASTABLE
input or “Complement” pulses on the ASTABLE input allow the circuit to
be used as a gatable multivibrator. The OSCILLATOR output period will
be half of the Q terminal output in the astable mode. However, a 50%
duty cycle is not guaranteed at this output.
The CD4047BMS triggers in the monostable mode when a positive
going edge occurs on the +TRIGGER input while the -TRIGGER is held
low. Input pulses may be of any duration relative to the output pulse.
If retrigger capability is desired, the RETRIGGER input is pulsed. The
retriggerable mode of operation is limited to positive going edge. The
CD4047BMS will retrigger as long as the RETRIGGER input is high,
with or without transitions (See Figure 31)
An external countdown option can be implemented by coupling “Q” to
an external “N” counter and resetting the counter with trigger pulse. The
counter output pulse is fed back to the ASTABLE input and has a dura-
tion equal to N times the period of the multivibrator.
A high level on the EXTERNAL RESET input assures no output pulse
during an “ON” power condition. This input can also be activated to ter-
minate the output pulse at any time. For monostable operation, when-
ever VDD is applied, an internal power on reset circuit will clock the Q
output low within one output period (tM).
