Description and Introduction

Octal D-Type Flip-Flops With Clear The SN74HC273DW is a high-speed octal D-type flip-flop manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** D-Type Flip-Flop  
- **Number of Bits:** 8  
- **Output Type:** Non-Inverted  
- **Trigger Type:** Positive Edge  
- **Supply Voltage Range:** 2V to 6V  
- **High-Level Output Current:** -7.8 mA  
- **Low-Level Output Current:** 7.8 mA  
- **Propagation Delay Time:** 20 ns (typical at 5V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC-20 (DW)  

### **Descriptions:**  
The SN74HC273DW features eight D-type flip-flops with a common clock (CP) and master reset (MR). On the positive edge of the clock pulse, the data (D) inputs are transferred to the outputs (Q). A low level on the MR input resets all outputs to low, independent of the clock.  

### **Features:**  
- **Wide Operating Voltage Range:** 2V to 6V  
- **High-Current Outputs:** Drive up to 15 LSTTL loads  
- **Low Power Consumption:** 80 µA (max) ICC  
- **Balanced Propagation Delays**  
- **Direct Clear Input**  
- **ESD Protection Exceeds JESD 22**  

This device is commonly used in register applications, data storage, and bus interfacing.
