Logic - Flip Flops

The 74HC273D is a registered 8-bit storage with transparent latches and is a CMOS integrated circuit chip. It was developed by NXP Semiconductors and is a LOGIC - Flip Flops device. It is most frequently used in digital circuits as a temporary storage register which reads data serially, stores it and then passes it out parallelly on the next clock cycle.

Application Field

The 74HC273D has many distinctive application uses and is used in a wide range of electronic circuits. It is used in circuits that require temporary storage and are required to operate at higher speeds, such as memory counters, temporary registers, and audio workstations. It is also used in programs from developing a data acquisition system, to designing a system for audio frequency input/output.

Working Principle

The 74HC273D has two 8-bit latches with a clock (CK) input. When the clock input is low, the outputs reflect the data inputs and are transparent to the application. When the clock input is high, the device switches to its non-transparent state and holds the data inputs. This device can also be used as a two-bit register, and can be used to temporarily store data when performing calculations.

On the output side, the data bits are available in parallel and can be used directly with other integrated circuits. The device operates on 5V DC power supply and can pass signals up to speeds of 20MHz. The output is Schmitt trigger providing improved noise immunity and fast switching times.

The 74HC273D is designed to meet the need for temporary storage registers in high-speed applications. It is versatile enough to be used effectively in applications from industrial systems to embedded systems and can meet the requirements of any application that requires temporary storage and fast data loading. The device is perfect for precise control of transistor-level logic and for rapid data-register logic control.
