Description and Introduction

Octal D-Type Flip-Flops With Clear The SN74HCT273DWR is a D-type flip-flop integrated circuit manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Series:** 74HCT  
- **Logic Type:** D-Type Flip-Flop  
- **Number of Bits:** 8  
- **Output Type:** Tri-State, Non-Inverted  
- **Clock Frequency:** Up to **25 MHz**  
- **Propagation Delay:** **20 ns** (typical)  
- **Supply Voltage Range:** **4.5V to 5.5V**  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Package / Case:** **SOIC-20**  
- **Mounting Type:** **Surface Mount**  
- **High-Level Input Voltage (Min):** **2V**  
- **Low-Level Input Voltage (Max):** **0.8V**  
- **Current - Output High, Low:** **6mA, 6mA**  

### **Descriptions:**  
The SN74HCT273DWR is an **8-bit D-type flip-flop** with a **common clock (CP)** and **master reset (MR)**. It features **tri-state outputs**, allowing multiple devices to share a common bus. The flip-flops store data on the **low-to-high transition of the clock (CP)**, and the **master reset (MR) asynchronously clears all flip-flops when low**.  

### **Features:**  
- **High-Speed CMOS Logic** (HCT family)  
- **Low Power Consumption**  
- **Wide Operating Voltage Range (4.5V to 5.5V)**  
- **Tri-State Outputs for Bus-Oriented Applications**  
- **Asynchronous Master Reset**  
- **Balanced Propagation Delays**  
- **Direct LSTTL Input Compatibility**  
- **ESD Protection Exceeds 2000V (HBM)**  

This information is strictly based on the manufacturer's datasheet and technical specifications.

Application Scenarios & Design Considerations

Octal D-Type Flip-Flops With Clear

Alternative Part Number

  • CD74HCT273M --: Same HCT logic family octal D flip-flop with clear, different CD prefix series, direct functional equivalent in SOIC package.
  • MC74HCT273ADWR2G --: HCT octal D flip-flop with asynchronous clear, different MC prefix and vendor, functionally and electrically compatible.
  • 74HCT273D --: Standard 74HCT273 octal D-type flip-flop in SOIC, different manufacturer naming, pin and function compatible.
  • 74HCT273D,653 --: Standard 74HCT273 octal D-type flip-flop in SOIC-20, same logic function and pinout from a different manufacturer series.
