APPLICATION INFORMATION
1 - CIRCUIT DESCRIPTION
Astable operation is enabled by a high level on the
ASTABLE input. 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. In the monostable

mode, positive-edge triggering is accomplished by
application of a leading-edge pulse to the
+TRIGGER input and a low level to the -TRIGGER
input. For negative-edge triggering, a trailing-edge
pulse is applied to the -TRIGGER and a high level
is applied to the +TRIGGER. Input pulses may be
of any duration relative to the output pulse. The
multivibrator can be retriggered (on the leading
edge only) by applying a common pulse to both
the RETRIGGER and +TRIGGER inputs. In this
mode the output pulse remains high as long as the
input pulse period is shorter than the period
determined by the RC components. An external
countdown option can be implemented by
