  7. OE (Output Enable) - Active LOW input to enable/disable the outputs
  8. VCC (Supply Voltage) - Positive supply voltage for the IC

Functional Features

  • Octal D-Type Flip-Flop: The IDT74LVC273APGG8 consists of eight individual D-type flip-flops, allowing it to store and transfer eight bits of data simultaneously.
  • Clear Function: The master reset (MR) input allows for clearing all flip-flops to a known state.
  • Output Enable: The output enable (OE) input enables or disables the outputs, providing control over when the stored data is visible at the outputs.
  • Low Voltage CMOS: The IC operates at low voltage levels, making it suitable for battery-powered devices and other low-power applications.

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data processing. - Low voltage operation reduces power consumption. - Compact TSSOP package saves board space. - Compatibility with various input/output standards enhances versatility.

Disadvantages: - Limited supply voltage range may restrict certain applications. - Not suitable for high-temperature environments due to the specified operating temperature range.

Working Principles

The IDT74LVC273APGG8 operates based on the principles of D-type flip-flops. When a clock pulse is applied to the CP input, the data present at the D0-D7 inputs is transferred to the corresponding Q0-Q7 outputs. The stored data remains unchanged until the next clock pulse. The master reset (MR) input clears all flip-flops to a known state, while the output enable (OE) input controls the visibility of the stored data at the outputs.

Detailed Application Field Plans

The IDT74LVC273APGG8 can be used in various applications, including but not limited to: 1. Microcontrollers and Processors: Used for data storage and synchronization in digital systems. 2. Communication Systems: Facilitates data buffering and synchronization in communication protocols. 3. Industrial Automation: Enables control and monitoring of devices in industrial processes. 4. Automotive Electronics: Supports data handling and synchronization in automotive systems. 5. Consumer Electronics: Used in devices such as TVs, set-top boxes, and gaming consoles for data processing.
