Working Principles

The 74HC273D,652 is a positive-edge triggered flip-flop integrated circuit. It consists of eight D-type flip-flops, each with an individual data input and output. The flip-flops store binary information based on the clock pulse input (CP). On the rising edge of the clock pulse, the data at the D inputs is transferred to the corresponding Q outputs. The master reset input (MR) allows for simultaneous clearing of all flip-flops, while the output enable input (OE) can disable the outputs. The complementary output (Q7') facilitates cascading multiple devices for larger data storage.

Detailed Application Field Plans

The 74HC273D,652 is widely used in various digital systems and applications, including:

1. Microcontrollers: Used for storing and manipulating data in microcontroller-based projects.
