Description and Introduction

Octal Buffers And Line/MOS Drivers With 3-State Outputs The SN74BCT2244N is a 20-pin octal buffer/driver with 3-state outputs, manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Logic Type:** Buffer/Line Driver  
- **Number of Bits:** 8  
- **Output Type:** 3-State  
- **Voltage Supply:** 4.5V to 5.5V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package / Case:** PDIP-20  
- **High-Level Output Current:** -15mA  
- **Low-Level Output Current:** 64mA  
- **Propagation Delay Time:** 7.5ns (max)  
- **Input Type:** TTL-Compatible  

### **Features:**  
- **BiCMOS Technology:** Combines high-speed performance with low power consumption.  
- **3-State Outputs:** Allows multiple outputs to be connected to a common bus.  
- **High Drive Capability:** Supports heavy capacitive loads.  
- **TTL-Compatible Inputs:** Ensures compatibility with TTL logic levels.  
- **ESD Protection:** Provides protection against electrostatic discharge.  

This device is commonly used in bus-oriented applications where buffering and signal driving are required.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • 74BCT2244APC --: Same octal buffer/driver function with 25-ohm series resistors and BCT TTL-compatible inputs, in a DIP package; a direct functional replacement from an alternate vendor.
  • MC74BCT2244N --: Pin-compatible octal buffer/driver with equivalent BCT input thresholds and series damping resistors, offered in the same DIP-20 footprint.
  • CY74FCT2244ATPC --: FCT-series octal buffer/driver with 25-ohm output resistors and similar speed/current ratings; usable as a functional substitute in DIP-20 with minor timing differences.
