SN54107Dual J-K Flip-Flops With Clear | Logic | 1 | Active | The '107 contain two independent J-K flip-flops with individual J-K, clock, and direct clear inputs. The '107 is a positive pulse-triggered flip-flop. The J-K input data is loaded into the master while the clock is high and transferred to the slave and the outputs on the high-to-low clock transition. For these devices the J and K inputs must be stable while the clock is high.
The 'LS107A contain two independent negative-edge-triggered flip-flops. The J and K inputs must be stable prior to the high-to-low clock transition for predictable operation. When the clear is low, it overrides the clock and data inputs forcing the Q output low and the Q\ output high.

SN54121Monostable Multivibrators With Schmitt-trigger Inputs | Multivibrators | 3 | Active | These multivibrators feature dual negative-transition-triggered inputs and a single positive-transition-triggered input which can be used as an inhibit input. Complementary output pulses are provided.
Pulse triggering occurs at a particular voltage level and is not directly related to the transition time of the input pulse. Schmitt-trigger input circuitry (TTL hysteresis) for the B input allow jitter-free triggering from inputs with transition rates as slow as 1 volt/second, providing the circuit with an excellent noise immunity of typically 1.2 volts. A high immunity to VCCnoise of typically 1.5 volts is also provided by internal latching circuitry.
Once fired, the outputs are independent of further transitions of the inputs and are a function only of the timing components. Input pulses may be of any duration relative to the output puls. Output pulse length may be varied from 40 nanoseconds to 28 seconds by choosing appropriate timing components. With no external timing components (i.e., Rintconnected to VCC, Cextand Rext/Cextopen), an output pulse of typically 30 or 35 nanoseconds is achieved which may be used as a d-c triggered reset signal. Output rise and fall times are TTL compatible and independent of pulse length.
Pulse width stability is achieved through internal compensation and is virtually independent of VCCand temperature. In most application, pulse stability will only be limited by the accuracy of external timing components.
Jitter-free operation is maintained over the full temperature and VCCranges for more than six decades of timing capacitance (10 pF to 10 µF) and more than one decade of timing resistance (2 kmay be used. Also, the range of jitter-free output pulse widths is extended if VCCis held to 5 volts and free-air temperature is 25°C. Duty cycles as high as 90% are achieved when using maximum recommended RT. Higher duty cycles are available if a certain amount of pulse-width jitter is allowed.

SN54123Retriggerable Monostable Multivibrators | Integrated Circuits (ICs) | 2 | 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.
