SN54/74LS122 SN54/74LS123 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.
