Description and Introduction

Octal Buffers And Line Drivers With 3-State Outputs The SN74S244DWR is a 3-state octal buffer and line driver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Buffer/Line Driver  
- **Number of Bits:** 8  
- **Output Type:** 3-State  
- **Voltage Supply Range:** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package / Case:** SOIC-20  
- **Mounting Type:** Surface Mount  
- **High-Level Output Current:** -15mA  
- **Low-Level Output Current:** 24mA  
- **Propagation Delay Time:** 6ns (max) at 5V  
- **Input Capacitance:** 5pF (typ)  

### **Descriptions and Features:**  
- Designed for bus-oriented applications  
- Provides high-speed, low-power operation  
- 3-state outputs allow multiple devices to share a common bus  
- TTL-compatible inputs and outputs  
- High drive capability for driving heavily loaded buses  
- Standard 20-pin SOIC package  

This device is commonly used in digital systems for signal buffering and driving high-capacitance loads.

Application Scenarios & Design Considerations

Octal Buffers And Line Drivers With 3-State Outputs

Alternative Part Number

  • 74S244DWR --: Same 74S244 octal buffer function in SOIC-20 wide body, direct pin-compatible replacement from an alternate logic vendor.
  • DM74S244WM --: Equivalent 74S244 octal buffer/driver in SOIC-20, same Schottky TTL family and pinout, suitable drop-in substitute.
  • SN74S244DW --: Same TI SN74S244 device in the same SOIC-20 package without the tape-and-reel suffix, identical electrical and pin characteristics.
  • 74S244D --: Same 74S octal buffer/driver function in SOIC package; NXP is a major logic supplier with compatible pinout and specs.
  • SN74LS244DW --: Lower-power LS variant in the same SOIC package and pinout; usable where slightly slower switching and reduced drive are acceptable.
