Description and Introduction

Octal D-Type Flip-Flops With Clear The SN74LS273NSR is a part manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Logic Type:** D-Type Flip-Flop  
- **Number of Elements:** 1  
- **Number of Bits per Element:** 8  
- **Trigger Type:** Positive Edge  
- **Supply Voltage (VCC):** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package / Case:** 20-SOIC (0.209", 5.30mm Width)  
- **Mounting Type:** Surface Mount  
- **Output Type:** Non-Inverted  
- **Propagation Delay Time:** 25ns (Max) at 5V  
- **High-Level Output Current:** -0.4mA  
- **Low-Level Output Current:** 8mA  

### **Descriptions:**  
The SN74LS273NSR is an octal D-type flip-flop with a common clock (CP) and a master reset (MR). It features edge-triggered flip-flops, meaning data is transferred to the outputs on the positive edge of the clock pulse. The master reset (active LOW) asynchronously clears all flip-flops.  

### **Features:**  
- **8-Bit Storage Register:** Can store 8 bits of data.  
- **Positive Edge-Triggered Clocking:** Ensures synchronous operation.  
- **Asynchronous Master Reset:** Clears all outputs when MR is LOW.  
- **TTL-Compatible Inputs & Outputs:** Works with standard TTL logic levels.  
- **Wide Operating Voltage Range:** 4.75V to 5.25V.  
- **High Noise Immunity:** Typical of LS-TTL technology.  
- **Surface-Mount Package (SOIC-20):** Suitable for compact PCB designs.
