Description and Introduction

OCTAL BUFFERS/DRIVERS WITH 3-STATE OUTPUTS The SN74F244DB is an octal buffer and line driver manufactured by Philips (PHI).  

### **Specifications:**  
- **Logic Type:** Buffer/Line Driver  
- **Number of Bits:** 8  
- **Output Type:** 3-State  
- **Voltage Supply:** 4.5V to 5.5V  
- **Operating Temperature:** -40°C to +85°C  
- **Package:** SSOP-20  

### **Descriptions:**  
- The SN74F244DB is designed for bus-oriented applications.  
- It features two independent 4-bit buffers with 3-state outputs.  
- The outputs can be disabled using the output enable (OE) pins.  

### **Features:**  
- High-speed operation  
- 3-state outputs for bus interfacing  
- Balanced propagation delays  
- Standard TTL input and output levels

This information is based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

OCTAL BUFFERS/DRIVERS WITH 3-STATE OUTPUTS

Alternative Part Number

  • MC74F244DWR2 --: Octal buffer/line driver with 3-state outputs in the same F logic family and wide SOIC package, functionally equivalent to the SN74F244DB.
  • 74F244SCX --: Direct octal buffer/line driver replacement with 3-state outputs, matching F-series speed and drive characteristics.
  • CD74FCT244M --: FCT-series octal buffer with 3-state outputs offering similar function and improved drive, usable as a functional substitute in most designs.
  • 74F244SC --: Same 74F244 octal buffer function in a comparable SOIC package, widely available and pin-compatible in most designs.
  • MC74F244DW --: Equivalent 74F244 octal buffer/driver from another major logic vendor, suitable drop-in replacement with matching speed and drive.
  • 74F244D --: Standard 74F244 octal buffer in SO package, electrically equivalent and commonly used as an alternative to the original PHI part.
