Description and Introduction

QUAD BUS BUFFER The TC74VHC125 is a quad bus buffer gate manufactured by Toshiba. It is part of the VHC (Very High-Speed CMOS) series and features 3-state outputs.  

### **Key Specifications:**  
- **Supply Voltage Range (VCC):** 2.0V to 5.5V  
- **High-Speed Operation:** tpd = 3.8 ns (typical) at 5V  
- **Low Power Consumption:** ICC = 2 μA (max) at 5V  
- **Output Drive Capability:** 8 mA at 5V  
- **Input Voltage Levels:**  
  - **High-Level Input Voltage (VIH):** 2.0V (min) at VCC = 5V  
  - **Low-Level Input Voltage (VIL):** 0.8V (max) at VCC = 5V  
- **3-State Outputs:** Allows bus-oriented applications  
- **Pin Configuration:** 14-pin package (DIP, SOP, TSSOP)  

### **Features:**  
- **CMOS Technology:** Low power consumption with high noise immunity  
- **Balanced Propagation Delays:** Ensures stable signal transmission  
- **Wide Operating Voltage Range:** Compatible with 3.3V and 5V systems  
- **ESD Protection:** HBM 2000V (min)  

### **Applications:**  
- Bus interface  
- Signal buffering  
- Data transmission systems

Application Scenarios & Design Considerations

QUAD BUS BUFFER

Alternative Part Number

  • SN74AHC125DR --: Quad bus buffer gate with 3-state outputs in the same AHC logic family; pin-compatible and widely available, direct functional replacement.
  • MC74VHC125DR2G --: VHC-series quad 3-state buffer with equivalent speed and drive characteristics; pin-compatible SOIC package option.
  • 74VHC125MTCX --: Same VHC logic family quad buffer with 3-state outputs; functionally equivalent and commonly used as a cross-reference.
