- **Output Current (High/Low):** ±6 mA  
- **Package Type:** 20-pin CDIP (Ceramic Dual In-Line Package)  

### **Descriptions:**  
The SN54HCT244J is a non-inverting octal buffer and line driver designed for bus-oriented applications. It features 3-state outputs, allowing multiple devices to share a common bus without interference.  

### **Features:**  
- **3-State Outputs:** Enable/disable control for bus interfacing  
- **TTL-Compatible Inputs:** Works with TTL logic levels  
- **Balanced Propagation Delays:** Ensures reliable signal timing  
- **Wide Operating Voltage Range:** Supports 4.5V to 5.5V operation  
- **High Noise Immunity:** CMOS technology provides robust performance  
- **Military Temperature Range:** Suitable for harsh environments  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application notes, refer to the official Texas Instruments documentation.

Application Scenarios & Design Considerations

Octal Buffers And Line Drivers With 3-State Outputs

Alternative Part Number

  • CD74HCT244E --: Same HCT octal buffer/driver function with 3-state outputs, widely available in PDIP package and a direct functional replacement.
  • MC74HCT244ANG --: HCT-series octal buffer/line driver with equivalent logic levels and pinout, suitable drop-in alternative in DIP package.
  • 74HCT244N --: Standard 74HCT244 octal buffer with 3-state outputs, electrically compatible and commonly used as a substitute.
