Description and Introduction

OCTAL BUS BUFFER (WITH SCHMITT TRIGGER INPUTS) The TC74HC7244AF is a high-speed CMOS octal bus buffer manufactured by Toshiba. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Logic Family:** HC (High-Speed CMOS)  
- **Number of Channels:** 8 (Octal)  
- **Supply Voltage Range:** 2V to 6V  
- **High-Level Input Voltage (VIH):** 2V (min) at VCC = 4.5V  
- **Low-Level Input Voltage (VIL):** 0.8V (max) at VCC = 4.5V  
- **High-Level Output Voltage (VOH):** 4.4V (min) at VCC = 4.5V, IOH = -4mA  
- **Low-Level Output Voltage (VOL):** 0.1V (max) at VCC = 4.5V, IOL = 4mA  
- **Propagation Delay Time (tpd):** 13ns (max) at VCC = 4.5V, CL = 50pF  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOP-20 (Small Outline Package, 20-pin)  

### **Description:**  
The TC74HC7244AF is an octal bus buffer with 3-state outputs, designed for high-speed digital signal transmission. It is commonly used for signal buffering and driving in digital circuits.  

### **Features:**  
- **3-State Outputs:** Allows multiple devices to share a common bus without interference.  
- **High-Speed Operation:** Optimized for fast signal propagation.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **Wide Operating Voltage Range:** Supports 2V to 6V, making it versatile for various applications.  
- **High Noise Immunity:** Ensures reliable operation in noisy environments.  
- **Output Current Capability:** Can drive up to 4mA (sink/source).  
- **Pin-Compatible with 74LS244:** Can replace TTL counterparts in many applications.  

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

Application Scenarios & Design Considerations

OCTAL BUS BUFFER (WITH SCHMITT TRIGGER INPUTS)

Alternative Part Number

  • SN74HC244N --: Same HC-series octal buffer/line driver function with 3-state outputs, widely available and pin-compatible in DIP package.
  • MC74HC244ADW --: Equivalent HC-series octal buffer/line driver with 3-state outputs, direct functional replacement in SOIC package.
  • CD74HC244E --: HC-family octal buffer/line driver offering the same logic function and 3-state outputs, suitable drop-in alternative.
  • SN74HC244DWR --: Wide-supply octal buffer/line driver with 3-state outputs, functionally equivalent to the HC244 function and available in SOIC, a common drop-in replacement.
  • MC74HC244ADWR2G --: HC-series octal buffer with 3-state outputs in SOIC package, same logic function and compatible pinout, good second-source option.
  • 74HC244D --: Standard 74HC244 octal buffer/line driver in SOIC, widely stocked and pin-compatible with the original HC244 function.
