Description and Introduction

Octal Schmitt Bus Buffer The TC74VHCV541FT 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:** VHC (Very High-Speed CMOS)  
- **Number of Channels:** 8 (Octal)  
- **Input/Output Type:** 3-state, non-inverting  
- **Supply Voltage Range (VCC):** 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 = 4.5V, IOH = -4mA  
- **Low-Level Output Voltage (VOL):** 0.1V (max) at VCC = 4.5V, IOL = 4mA  
- **Propagation Delay Time (tpd):** 5.5ns (max) at VCC = 5V, CL = 50pF  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** TSSOP-20  

### **Descriptions:**  
- The TC74VHCV541FT is an octal bus buffer with 3-state outputs designed for bus-oriented applications.  
- It features two active-low output enable pins (OE1 and OE2) for flexible control.  
- Non-inverting buffer ensures signal integrity without logic inversion.  
- Optimized for low power consumption and high-speed operation.  

### **Features:**  
- **Wide Operating Voltage Range:** 2.0V to 5.5V  
- **High-Speed Operation:** tpd = 5.5ns (max) at 5V  
- **Low Power Consumption:** ICC = 4µA (max) at 5.5V  
- **3-State Outputs:** Allows bus line sharing  
- **Balanced Propagation Delays:** Ensures signal synchronization  
- **Power-Down Protection:** Inputs and outputs include clamping diodes  
- **Pin-Compatible with 74VHC541**  

This information is strictly factual and based on Toshiba's provided datasheet for the TC74VHCV541FT.

Application Scenarios & Design Considerations

Octal Schmitt Bus Buffer

Alternative Part Number

  • 74VHC541FT --: Same VHC-family octal buffer/line driver with 3-state outputs in a similar TSSOP package, functionally equivalent and widely available.
  • SN74AHC541PW --: AHC-family octal buffer/line driver with 3-state outputs, comparable speed and drive, available in TSSOP, a common drop-in functional replacement.
  • MC74VHC541DT --: VHC octal buffer/line driver with 3-state outputs in TSSOP, matching the original logic family and function for direct substitution.
  • SN74AHCT541PWR --: Octal buffer/line driver in TSSOP-20 with 5V-tolerant inputs, functionally equivalent to the VHCV541 and widely available.
  • MC74VHC541DTR2G --: Octal buffer/line driver in TSSOP-20 with comparable VHC logic levels and pinout, suitable drop-in replacement.
