Description and Introduction

Octal Schmitt Bus Buffer The TC74VHCV541FK 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 Type:** Octal Bus Buffer (Non-Inverting)  
- **Technology:** CMOS  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **High-Speed Operation:**  
  - Propagation Delay (Max): 5.5 ns (at 5V)  
- **Low Power Consumption:**  
  - Quiescent Supply Current (Max): 4 µA (at 5.5V)  
- **Output Drive Capability:**  
  - Can drive up to 8 mA (at 3.3V) or 12 mA (at 5V)  
- **Input/Output Compatibility:**  
  - TTL-Compatible Inputs  
  - 5V-Tolerant Inputs (Even at VCC = 3.3V)  
- **Package Type:** SOP-20 (Small Outline Package, 20-pin)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The TC74VHCV541FK is a non-inverting octal buffer designed for bus interface applications.  
- It features two output enable pins (OE1 and OE2) for flexible control.  
- The device is optimized for high-speed operation while maintaining low power consumption.  
- It is suitable for voltage translation between 3.3V and 5V systems due to its 5V-tolerant inputs.  

### **Features:**  
- **Non-Inverting Buffer:** Maintains signal polarity.  
- **3-State Outputs:** Allows bus-oriented operation.  
- **Wide Operating Voltage Range (2.0V–5.5V):** Supports mixed-voltage systems.  
- **Balanced Propagation Delays:** Ensures signal integrity.  
- **Low Noise:** Designed for minimal switching noise.  
- **High-Impedance Outputs:** When disabled, reduces bus contention.  

This information is strictly factual and derived from Toshiba's official documentation.

Application Scenarios & Design Considerations

Octal Schmitt Bus Buffer

Alternative Part Number

  • SN74LVC541APW --: Octal buffer/line driver with 3-state outputs in TSSOP, functionally equivalent to the VHC541 with similar 5V-tolerant inputs and wide supply range.
  • 74LVC541APW --: Octal buffer/line driver, 3-state, TSSOP package, direct functional and pin-compatible replacement for the VHC541 function.
  • MC74VHC541DT --: Octal buffer/line driver with 3-state outputs in TSSOP, same VHC logic family performance and pinout as the original.
