Monostable Multivibrator Schmitt-trigger inputs
IC MONOSTABLE MULTIVIB 14SO
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 VCC noise 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., Rint connected to VCC, Cext and Rext/Cext open), 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 VCC and 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 VCC ranges for more than six decades of timing capacitance (10 pF to 10 F) and more than one decade of timing resistance (2 k to 30 k for the SN54121 and 2 k to 40 k for the SN74121). Throughout these ranges, pulse width is defined by the relationship tw(out) = CextRTin2 = 0.7 CextRT. In circuits where pulse cutoff is not critical, timing capacitance up to 1000 F and timing resistance as low as 1.4 k may be used. Also, the range of jitter-free output pulse widths is extended if VCC is held to 5 volts and free-air temperature is 25C. 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.
