RETRIGGERABLE MONOSTABLE

MULTIVIBRATORS

These dc triggered multivibrators feature pulse width control by three meth-

ods. The basic pulse width is programmed by selection of external resistance

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-

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.

NOTES:

ORDERING INFORMATION

1. An external timing capacitor may be connected between C

2. To use the internal timing resistor of the LS122, connect R to V

3. For improved pulse width accuracy connect an external resistor between R /C

and R /C (positive).
