Description and Introduction

Octal Buffers/Drivers With 3-State Outputs The SN74ACT244NSR is a 20-pin octal buffer and line driver manufactured by Texas Instruments.  

### **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/Case:** SOIC-20  
- **Mounting Type:** Surface Mount  
- **High-Level Output Current:** -24mA  
- **Low-Level Output Current:** 24mA  
- **Propagation Delay Time:** 8.5ns (max) at 5V  
- **Input Capacitance:** 4.5pF (typ)  

### **Descriptions:**  
The SN74ACT244NSR is an octal buffer and line driver designed for high-speed, low-power operation. It features 3-state outputs that allow connection to a bus-organized system. The device is compatible with TTL inputs and provides improved noise immunity.  

### **Features:**  
- **3-State Outputs** for bus-oriented applications  
- **TTL-Compatible Inputs**  
- **Balanced Propagation Delays**  
- **High Drive Outputs** (±24mA)  
- **Wide Operating Voltage Range** (4.5V to 5.5V)  
- **ESD Protection** exceeds 2000V per MIL-STD-883, Method 3015  

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

Application Scenarios & Design Considerations

Octal Buffers/Drivers With 3-State Outputs

Alternative Part Number

  • MC74ACT244DWR2G --: Same ACT logic family octal buffer/driver with 3-state outputs in a wide SOIC-20 package, functionally equivalent and widely available.
  • 74ACT244SCX --: Pin-compatible octal buffer/line driver with 3-state outputs, same ACT speed grade and SOIC-20 footprint.
  • CD74ACT244M96 --: Same manufacturer ACT-family octal buffer/driver with 3-state outputs in SOIC-20, offering identical logic behavior with a different series prefix.
  • MC74ACT244ADWR2G --: Octal buffer/line driver with 3-state outputs in the same ACT logic family and SOIC-20 wide package, directly pin-compatible and functionally equivalent to the SN74ACT244NSR.
  • CD74ACT244M --: TI ACT-family octal buffer/line driver with 3-state outputs in SOIC-20, same logic function and compatible electrical characteristics from the same manufacturer.
