The pin out diagram works any any style 74xx or 74xx DIP chip, but the timing graphs are only valid for the TTL families indicated. TTL One Shot. The shown above provides a single Monostable Multivibrator function. While the shown below provides a retriggerable Monostable Multivibrator function with clear.

A Monostable Multivibrator is also called a One Shot. Note the uses a 4k internal resistor, while the uses a 20k resistor. Monostable Pulse Timing: The two graphs below show the resultant pulse width for different values of resistors and capacitors. The first chart works for either the 74L or 74L; however, the second chart only applies to the 74L Also refer to Transistor Multivibrator Circuits.

The circuit could be used for any TTL family, such as LS, or H, but the load capacitor might need to be changed to reflect that. The Diodes used in the circuit are 1N or equivalent. The load Capacitance CL is 50pF, including scope probe, wiring, and any stray capacitance. There are two different methods of connecting Rx and Cx. The first method for a Cx of less than pF [below] and a second connection [below that] for an external capacitor, Cx, of greater than pF.

Digital integrated circuits can be used in the design of an analogue frequency meter with a frequency range to several MHz. The Figure 1 shows the circuit diagram of the frequency meter, the circuit based on the digital IC This IC is the monostable multivibrator that may generate a pulse of a different width from 35 ns and wider that depends on RC components. All this allows to create very simple frequency meter circuit with several frequency ranges:. The number of frequency ranges can be increased by using a rotary switch SA1 with more than four positions, and by adding some additional RC components. The device can measure sinusoidal wave and square wave input signals. The pulse width produced by the monostable multivibrator depends on the values of capacitors C
