Description and Introduction

OCTAL BUS BUFFER. INVERTED/NON-INVERTED, 3-STATE OUTPUTS The TC74VHC244FW is a high-speed CMOS octal bus buffer manufactured by Toshiba. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Logic Family:** VHC (Very High-Speed CMOS)  
- **Number of Channels:** 8 (Octal)  
- **Input/Output Type:** 3-state  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **High-Level Input Voltage (VIH):** 2.0V (min) at VCC = 5.5V  
- **Low-Level Input Voltage (VIL):** 0.8V (max) at VCC = 5.5V  
- **High-Level Output Voltage (VOH):** 4.4V (min) at VCC = 5.0V  
- **Low-Level Output Voltage (VOL):** 0.1V (max) at VCC = 5.0V  
- **Propagation Delay Time (tpd):** 4.3 ns (typ) at VCC = 5.0V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** TSSOP-20  

### **Descriptions:**  
- The TC74VHC244FW is an octal bus buffer designed for high-speed operation with 3-state outputs.  
- It is compatible with TTL levels and provides bidirectional signal buffering.  
- The device is optimized for low power consumption while maintaining high-speed performance.  

### **Features:**  
- **High-Speed Operation:** tpd = 4.3 ns (typ) at VCC = 5V  
- **Wide Operating Voltage Range:** 2.0V to 5.5V  
- **Low Power Consumption:** ICC = 4 μA (max) at TA = 25°C  
- **3-State Outputs:** Allows bus-oriented applications  
- **TTL-Compatible Inputs:** Can interface with TTL logic levels  
- **Balanced Propagation Delays:** Ensures stable signal transmission  
- **ESD Protection:** HBM 2000V (min)  

This information is strictly based on the manufacturer's datasheet for the TC74VHC244FW.

Application Scenarios & Design Considerations

OCTAL BUS BUFFER. INVERTED/NON-INVERTED, 3-STATE OUTPUTS

Alternative Part Number

  • SN74AHC244PW --: Same octal buffer/driver function in TSSOP package with similar AHC logic family and widely available as a direct functional replacement.
  • 74AHC244PW --: Equivalent octal buffer/line driver in TSSOP with AHC speed grade, matching pinout and electrical characteristics.
  • MC74VHC244DTR2G --: VHC-family octal buffer in TSSOP with comparable propagation delay and drive strength, suitable drop-in alternative.
  • 74VHC244MTC --: Same VHC-family octal buffer in TSSOP, direct functional and package-compatible replacement with comparable propagation delay.
