Description and Introduction

4 BIT BINARY FULL ADDER The M74HC283 is a high-speed CMOS 4-bit binary full adder manufactured by OKI.  

### **Specifications:**  
- **Logic Family:** HC (High-Speed CMOS)  
- **Supply Voltage Range:** 2V to 6V  
- **High-Speed Operation:** Typical propagation delay of 11ns at 5V  
- **Low Power Consumption:** 4µA max (static)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** DIP (Dual In-line Package), SOP (Small Outline Package)  

### **Descriptions:**  
- The M74HC283 performs 4-bit binary addition with carry-in (Cn) and carry-out (Cn+4).  
- It generates sum outputs (Σ0 to Σ3) and a carry-out (Cn+4) for cascading multiple adders.  
- Compatible with TTL levels due to CMOS technology.  

### **Features:**  
- **4-Bit Full Adder:** Performs addition of two 4-bit binary numbers.  
- **Carry Look-Ahead:** Enhances speed by reducing carry propagation delay.  
- **Wide Voltage Range:** Operates from 2V to 6V, making it versatile for different logic levels.  
- **Low Power Consumption:** Suitable for battery-operated devices.  
- **Pin-Compatible:** Can replace older 74LS283 in many applications.  

This information is based on OKI's official documentation for the M74HC283.

Application Scenarios & Design Considerations

4 BIT BINARY FULL ADDER

Alternative Part Number

  • CD74HC283E --: Same 4-bit binary full adder function in the HC logic family with identical pinout, widely available and a direct functional drop-in.
  • SN74HC283N --: HC-series 4-bit full adder with matching truth table and DIP pinout, a common industry-standard substitute for the M74HC283.
  • MC74HC283AN --: Equivalent 4-bit full adder in HC CMOS logic with the same pin configuration, suitable as a second-source replacement.
