SN74LV174APWR Application Field and Working Principle

A SN74LV174APWR flip flop is a type of logic circuit in which a single bit of information can be stored for a long period of time. This type of flip flop is commonly used in digital circuits as a latch or register to allow for the transfer of data from one stage of a circuit to the next.

Applications

The SN74LV174APWR flip flop is commonly used in digital circuit applications including computer memory, RAM, ROM, and SRAM memory systems. It can also be used in programmable logic controllers (PLCs) and control circuits for process automation. The flip flop can also be used in other digital circuits such as addressable alarm systems, digital multimeters, electronic banking and remotely operated systems.

Working Principle

The SN74LV174APWR flip flop contains three primary components: an active-low set/reset (SR) flip flop, an active-low output enable (OE) flip flop, and an active-high clock (CLK) flip flop. Depending on the circuit configuration, the clock flip flop can either be used as a master or a slave.

When the clock flip flop is used as a master, the clock signal will set or reset the SR flip flop depending on the state of the clock signal. The OE flip flop will then be enabled or disabled depending on the state of the SR flip flop. When the clock flip flop is used as a slave, the OE flip flop is enabled or disabled based on the state of the clock signal, while the SR flip flop is enabled or disabled based on the OE flip flop.

When the OE flip flop is enabled, the output of the flip flop will change based on the logic levels present at the data input and the clock signal. When the OE flip flop is disabled, the output of the flip flop will remain unchanged regardless of the logic levels present at the data input and the clock signal.

Conclusion

The SN74LV174APWR flip flop is an important component in a variety of digital circuits, from computer memory to automated control systems. It provides the ability to store a single bit of information over long periods of time, and it is also capable of controlling the output signal based on the logic levels present at the data input and the clock signal.
