REI Datasheet SN54122, ‘123, ‘130, ‘L122, ‘L123, ‘LS122, ‘LS123 SN74122, ‘123, ‘130, ‘LS122, ‘LS123 Retriggerable Monostable Multivibrators These d-c triggered multivibrators feature output pulse width control by three methods. The basic pulse time is programmed by selection of external resistance and capacitance values. The ‘122, ‘L122, and ‘LS122 have internal timing resistors that allow the circuits to be used with only an external capacitor, if so desired. Once triggered, the basic 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. The ‘LS122 and ‘LS123 are provided enough Schmitt hysteresis to ensure jitter-free triggering from the B input with transition rates as slow as 0.1 millivolt per nanosecond.
