SN74123Dual retriggerable monostable multivibrators | Integrated Circuits (ICs) | 1 | Active | These d-c triggered multivibrators feature output pulse-duration control by three methods. The basic pulse time is programmed by selection of external resistance and capacitance values (see typical application data). The '122 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 duration 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. Figure 1 illustrates pulse control by retriggering and early 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.
The Rintis nominally 10 kfor '122 and 'LS122.

SN74146-ch, 4.75-V to 5.25-V bipolar inverters with Schmitt-Trigger inputs | Integrated Circuits (ICs) | 5 | Active | Each circuit in SNx414 and SNx4LS14 functions as an inverter. However, because of the Schmitt-Trigger action, they have different input threshold levels for positive-going (VT+) and negative-going (VT–) signals.
These circuits are temperature compensated and can be triggered from the slowest of input ramps and still give clean, jitter-free output signals.
