Multivibrators are a class of logic circuits capable of producing two output waveforms, usually complementary in nature, with an input applied. The two waveforms are usually square pulses, the instant at which they occur being determined by the values of any external components connected to the circuit. One of the waveforms is normally referred to as the "mark" and the other as the "space". On occasion, the waveforms generated can be place as rectangular ones instead. An example of such an application is when two waveforms with different pulse widths and semiperiods are required. Within the multivibrator family, a wide variety of specialized circuits are derived from type configurations, the most common of them being the astable, monostable, bistable and schmitt. Each one of these configurations works using the same basic principles, which involve the use of based circuitry, and the differences are in the way they are connected to achieve specific frequency and duty cycle characteristics.

The LTC6993CDCB-4#TRMPBF is an example of one such designed piece of logic based multivibrator, suitable for a large range of commercial, industrial and general-purpose applications. It constructed on an ULTRA ThinSOT and is generally used within various time base applications, such as time-out alarms, blinks/flash circuits, frequency-dependent pulse shaping and many more. It works using the principles of hysteresis, which is primarily created by the resistors and capacitors connected to the circuit.

The main operation of the LTC6993CDCB-4#TRMPBF is based on the voltage threshold of the circuit, which is then used to induce various time-dependent waveforms. The voltage threshold of the circuit is based on the hysteresis setting of the circuit, mainly determined by the two external resistors. As an example, if the circuit is set to switch with a 1V input limit and 0.1V hysteresis, then the circuit will respond to the mark and space values as 1V and 0.9V respectively.

When the input voltage is below the threshold, the output is driven low, if the voltage exceeds the threshold, the output is driven high. When the circuit is in a stable state, the output stays in its High or Low level. However, when the input voltage is at the threshold, the output level may see-saw between the mark and space states, thus forming the basic elements of oscillation.

The LTC6993CDCB-4#TRMPBF also has various additional features which can be used to extend its useability. This includes an oscillation auto-acceleration feature, allowing the oscillation to start with a wide frequency range and acceleration over time, and a multiplexer & prescaler MUX-instruction logic circuitry, which provides fixed frequency and PWM outputs. This allows the circuit to be used in a wider range of applications, including servo motor control, buck and boost converters, phase-locked loops and many more.

In conclusion, the LTC6993CDCB-4#TRMPBF is a highly functional and versatile logic based multivibrator. It is capable of generating two complementary output waveforms, usually square pulses, with the instant of their occurrence determined by the values of external components. The core of its operation is based on hysteresis, which allows the circuit to create a wide range of time-dependent waveforms. It also has a number of additional features, such as auto-acceleration and MUX-instruction logic to further extend its normally already wide range of applications.
