Description and Introduction

Octal Buffers And Line/MOS Drivers With 3-State Outputs The SN74ABT2244ADW is a 20-bit buffer/driver manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:  

### **Specifications:**  
- **Logic Type:** Buffer/Line Driver  
- **Number of Bits:** 20  
- **Output Type:** 3-State  
- **Voltage Supply:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package/Case:** SOIC (DW)  
- **Mounting Type:** Surface Mount  
- **High-Level Output Current:** -32mA  
- **Low-Level Output Current:** 64mA  
- **Propagation Delay Time:** 4.5ns (max) at 5V  
- **Input Capacitance:** 4.5pF (typ)  

### **Descriptions:**  
The SN74ABT2244ADW is a high-performance, 20-bit buffer/driver designed for bus-oriented applications. It features 3-state outputs, allowing multiple devices to share a common bus without interference. It operates with a 5V supply and provides high-speed, low-power performance suitable for driving heavy loads.  

### **Features:**  
- **3-State Outputs** for bus sharing  
- **High Drive Capability** (up to 64mA sink current)  
- **Balanced Propagation Delays**  
- **ESD Protection** exceeds 2000V (MIL-STD-883, Method 3015)  
- **BiCMOS Technology** for low power consumption  
- **Flow-Through Pinout** for optimized PCB layout  

This device is commonly used in memory address driving, clock buffering, and general-purpose bus interfacing applications.

Application Scenarios & Design Considerations

Octal Buffers And Line/MOS Drivers With 3-State Outputs

Alternative Part Number

  • 74ABT2244ADW --: Same ABT2244 octal buffer with 3-state outputs in SOIC-20 wide body, pin-compatible and functionally equivalent to the original.
  • CY74FCT2244ATSOCT --: FCT2244 octal buffer with series damping resistors, similar drive and 3-state outputs, suitable drop-in replacement in most designs.
  • 74ACT2244SC --: ACT2244 octal buffer with 25-ohm series resistors and 3-state outputs, comparable speed and logic function in SOIC-20 package.
  • 74ABT2244ADB --: Same ABT2244 octal buffer/driver function with 25-ohm series resistors, SSOP package, pin-compatible with the SOIC DW version for many layouts.
  • 74ABT2244APW --: Equivalent ABT2244 function in TSSOP package; electrically similar with 25-ohm output resistors, suitable when a smaller footprint is acceptable.
  • 74ABT244ADW --: Same octal buffer/driver family without integrated series resistors; can replace the 2244 in designs where external or no series damping is acceptable.
