Description and Introduction

Octal Buffers And Line Drivers With 3-State Outputs The SN74HCT244PW is an octal buffer and line driver manufactured by Texas Instruments. Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Technology Family:** HCT  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Input Voltage Range:** 0V to VCC  
- **Output Current (High/Low):** ±6mA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** TSSOP (PW)  
- **Number of Channels:** 8 (Octal)  
- **Logic Type:** Buffer/Line Driver  
- **Propagation Delay:** 13ns (typical)  
- **Input Type:** CMOS  
- **Output Type:** 3-State  

### **Descriptions:**  
- The SN74HCT244PW is a high-speed CMOS logic octal buffer and line driver with 3-state outputs.  
- It is designed for bus-oriented applications where multiple outputs must be controlled.  
- The device features two active-low output enables (OE) for independent control of the four buffers each.  
- It is compatible with TTL inputs, making it suitable for interfacing between TTL and CMOS systems.  

### **Features:**  
- **3-State Outputs:** Allows connection to a bus system.  
- **High-Current Outputs:** Can drive up to 15 LSTTL loads.  
- **Balanced Propagation Delays:** Ensures reliable performance in high-speed applications.  
- **Low Power Consumption:** Typical ICC of 80µA.  
- **ESD Protection:** Exceeds 2000V per JESD 22.  
- **Wide Operating Voltage Range:** Supports 4.5V to 5.5V operation.  

This information is strictly based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

Octal Buffers And Line Drivers With 3-State Outputs

Alternative Part Number

  • MC74HCT244ADTR2G --: Direct logic-equivalent octal buffer/driver in the same HCT family with TSSOP package, widely available and pin-compatible.
  • 74HCT244PW,118 --: Same 74HCT244 function in TSSOP package from a major alternate source, electrically compatible with the TI device.
  • CD74HCT244M96 --: TI's own CD-series HCT244 octal buffer with equivalent logic characteristics, though in SOIC package requiring footprint adaptation.
