Monostable/astable multivibrator

Astable operation is enabled by a HIGH level on the

ASTABLE input. The period of the square wave at O and

O outputs is a function of the external components

employed. ‘True’ input pulses on the ASTABLE 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 O output

in the astable mode. However, a 50% duty factor is not

guaranteed at this output.

An external count down option can be implemented by

coupling O to an external ‘N’ counter and resetting the

counter with the trigger pulse. The counter output pulse is

fed back to the ASTABLE input and has a duration equal

to N times the period of the multivibrator. A HIGH level on

the MR input assures no output pulse during an ON-power

condition. This input can also be activated to terminate the

output pulse at any time. In the monostable mode, a HIGH

level or power-ON reset pulse must be applied to MR,

whenever V_DDis applied.

In the monostable mode, positive edge-triggering is

accomplished by applying 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 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.
