Description and Introduction

Octal Buffers And Line/MOS Drivers With 3-State Outputs 20-SSOP -40 to 85 The SN74ABT2244ADBRG4 is a 20-bit buffer/driver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Technology Family:** ABT (Advanced BiCMOS Technology)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Number of Channels:** 20  
- **Output Type:** 3-State  
- **Package Type:** SSOP (Shrink Small Outline Package)  
- **Package / Case:** SSOP-20  
- **Logic Type:** Buffer/Line Driver  
- **Propagation Delay Time:** 4.5 ns (max)  
- **High-Level Output Current:** -32 mA  
- **Low-Level Output Current:** 64 mA  

### **Descriptions:**  
The SN74ABT2244ADBRG4 is a 20-bit buffer/driver designed for high-speed, low-power operation. It features 3-state outputs for bus-oriented applications and is compatible with TTL input and output levels.  

### **Features:**  
- **High-Speed Operation:** Optimized for 5V operation with fast propagation delays.  
- **3-State Outputs:** Allows multiple devices to share a common bus.  
- **BiCMOS Technology:** Combines low power consumption with high drive capability.  
- **TTL-Compatible Inputs:** Ensures compatibility with TTL logic levels.  
- **ESD Protection:** Exceeds 2000V per JESD 22-A114.  
- **Latch-Up Performance:** Exceeds 500 mA per JESD 78.  

This device is commonly used in data buffering, bus driving, and memory interfacing applications.

Application Scenarios & Design Considerations

Octal Buffers And Line/MOS Drivers With 3-State Outputs 20-SSOP -40 to 85

Alternative Part Number

  • 74ABT2244APW,112 --: Same ABT2244 octal buffer/driver function with 25-ohm series resistors, different NXP naming and package, direct functional replacement.
  • CY74FCT2244ATQCT --: FCT2244 octal buffer with series damping resistors, similar drive and speed, different series prefix makes it easy to distinguish.
  • 74ABT2244AD,118 --: ABT2244 octal buffer/driver with 25-ohm output resistors in SOIC, different manufacturer naming and package from the TI source.
  • 74ABT2244ADB --: Same ABT2244 octal buffer/driver function with 25-ohm series resistors in SSOP-20 package, pin-compatible and widely available from NXP.
  • 74ABT2244CPW --: Equivalent ABT2244 function in TSSOP-20 package with similar electrical characteristics; check package footprint before substitution.
  • 74ABT244ADB --: Standard ABT244 octal buffer in SSOP-20 without series resistors; usable if the 25-ohm output damping is not required by the design.
