概述
Description
Key features include eight flip-flops for storing data, a synchronous clock input for precise timing, and an asynchronous master reset that clears all outputs when activated. The device operates over a voltage range of 4.5V to 5.5V, making it suitable for 5V TTL applications. It is used in applications requiring temporary data storage, data synchronization, and as a buffer or latch in digital circuits.
Its compact design, speed, and compatibility make the 74HCT273D a reliable choice in various digital applications, especially where simple parallel data storage and retrieval are needed.

Features
1. Functionality: It contains eight edge-triggered D-type flip-flops. Data at the D inputs is transferred to the Q outputs on the positive-going edge of the clock pulse.
2. Clear Input: The device has an asynchronous master reset (active low, MR) that clears all the flip-flops, setting the Q outputs low regardless of the clock or data inputs.
3. Operating Voltage: The device operates typically within a supply voltage range of 4.5V to 5.5V.
4. Performance: It offers high-speed operation with low power consumption, typical of HCT logic families.
5. Pin Configuration: Available in a 20-pin package.
6. Temperature Range: It operates over a wide temperature range, typically from -40°C to +125°C.
7. Compatibility: The 74HCT273D is compatible with TTL input levels, making it suitable for interfacing with other TTL devices.
8. Applications: It is commonly used in applications requiring data latching and storage, such as registers or memory buffering.
These features make it a versatile component for digital systems.
Pinout
- Pin 1 (MR): Master Reset (active low)
- Pins 2 to 9 (D0 to D7): Data inputs
- Pin 10 (GND): Ground
- Pin 11 to 18 (Q0 to Q7): Data outputs
- Pin 19 (CP): Clock pulse input (active edge triggered)
- Pin 20 (VCC): Supply voltage
The primary function of the 74HCT273D is to store data from the D inputs to the Q outputs on the rising edge of the clock pulse. The master reset (MR) is used to reset all Q outputs to low when driven low. The IC is designed for use in high-speed memory and register applications.
