74HC423D,653

Logic - Multivibrators are a type of two state systems which are used as a basis for many digital circuits and systems. 74HC423D and 653 are two such devices that incorporate transistors and logic gates to create an oscillating logic signal.

The 74HC423D is a monostable multivibrator with two inputs, a SET pin and a RESET pin. The output of the multivibrator is high when SET is high and RESET is low. Conversely, the output is low when RESET is high and SET is low. If both inputs are high or both inputs are low, the output will not change state. This device has a maximum supply voltage of 18V, as well as both low power Schottky and CMOS technologies.

Similarly, the 653 is a monostable multivibrator but with a slightly different set of features. It has the same inputs of SET and RESET, but it has an additional control input of RESET CHAIN. This additional input allows for resetting the multivibrator with different input logic levels. The maximum supply voltage of the 653 is 16V.

The primary application of logic - multivibrators is in the area of timing systems. The 74HC423D and 653 are used to create timing sequences that can be used for timing applications such as clocks, timers, and counters. For example, the 74HC423D and 653 can be used as programmable timers to set a specified time duration for an application. The 74HC423D and 653 can also be used to create oscillators that can be tuned to a specific frequency and used for frequency generation, signal synchronization, and signal routing.

The working principles of both 74HC423D and 653 devices are similar. Both devices consist of transistors and logic gates that form an oscillator circuit. The output of the multivibrator is determined by the logic states of the SET and RESET inputs. If SET is high and RESET is low, the output of the multivibrator will be high. Conversely, if SET is low and RESET is high, the output will be low. The output will remain in this state until the SET and RESET input logic states are reversed.

The 74HC423D and 653 are useful devices for a wide variety of applications. They are used in logic control systems, timing circuits, and signal routing. These devices are advantageous because they are inexpensive, widely available, and easy to use. They also have a very low power consumption, making them suitable for a variety of low power applications.

In conclusion, 74HC423D and 653 are two types of logic - multivibrators that are used in many digital circuits and systems. These devices have two sets of inputs (SET and RESET) which are used to determine the output of the multivibrator, as well as an additional input (RESET CHAIN) for the 653. These devices are useful for applications such as clocks, timers, and counters. They are also advantageous because they are inexpensive, widely available, and have low power consumption.
