The 74LVC821AD,112 is an integrated circuit belonging to the type known as Logic - Flip Flops. It is commonly used in digital and computer circuitry to facilitate a wide range of functions. The Logic - Flip Flop is a type of digital circuit which performs binary operations in two states of either On or Off. It is also known as a bistable device as it is capable of maintaining two distinct states of either On or Off. This integrated circuit also contains a storage element which can store digital data for later recall.

The 74LVC821AD,112 Logic - Flip Flop is designed for use with the family of TTL logic circuits using 5V power supplies varying from 4.5V to 5V. It is composed of two cross-coupled complementary metal oxide semiconductor (CMOS) type transistors that act as a static latch. The two transistors being referred to are an input n-channel MOS transistor (PMOS) and an output p-channel MOS transistor (NMO). The input transistor is used to accept logic signals, while the output transistor is used to transfer the logic signal from the input in either the high or low state. The output transistors are also capable of controlling current being sourced to the logic circuit, thus enabling it to be used as a drive circuit.

The 74LVC821AD,112 also uses two additional MOS transistors to control the gating of the output voltage. This allows the circuit to produce various logic states, such as high-impedance (Hi-Z), low-impedance (Lo-Z) or logic LOW and logic HIGH. The input transistors are also provided with a diode-closure offering protection against high voltages and related transients.

The 74LVC821AD,112 is used in multiple applications, such as providing data latches, gating, shift registers, counters and other complex timing circuits. They also have wide use in pulse amplifiers, shift-register control systems, relays, and programmable logic controllers (PLCs). The design of this circuit makes it highly suited for use in low-power applications where low-voltage and low-power consumption are a priority. This type of logic-flip flop can be found in many electronic devices today, from mobile phones to personal computers.

The 74LVC821AD,112 utilizes clocking to provide an efficient, yet simple solution for controlling logic functions. The clock enables the circuit to move from one logic state to another by providing the circuitry with an updated signal. The flip-flop’s output changes only when a clock signal is present, thus allowing the timing or the flow control of logic operations. Clocking is essential for synchronizing data, signals and states. Without clocking, data transfer and signal synchronizing would not be possible, as the data to be transferred would have to be manually changed.

The 74LVC821AD,112 Logic - Flip Flop is a great device choice for many types of digital applications. Its low-power consumption, and its ability to control logic states and data transfers makes it a perfect choice for many types of control systems, sequencing and timing applications.
