RETRIGGERABLE MONOSTABLE
MULTIVIBRATORS
These dc triggered multivibrators feature pulse width control by three meth- RETRIGGERABLE MONOSTABLE
ods. The basic pulse width is programmed by selection of external resistance
MULTIVIBRATORS
and capacitance values. The LS122 has an internal timing resistor that allows
the circuits to be used with only an external capacitor. Once triggered, the ba- LOW POWER SCHOTTKY
sic pulse width may be extended by retriggering the gated low-level-active (A)
or high-level-active (B) inputs, or be reduced by use of the overriding clear.
