Description and Introduction

Octal Schmitt Bus Transceiver The TC74VHCV245FK is a CMOS digital integrated circuit manufactured by Toshiba. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Logic Type:** Octal Bus Transceiver  
- **Technology:** CMOS  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **High-Speed Operation:**  
  - tpd = 3.8 ns (max) at VCC = 5V  
- **Low Power Consumption:**  
  - ICC = 4 μA (max) at Ta = 25°C  
- **Output Drive Capability:**  
  - 8 mA at VCC = 3.3V  
  - 12 mA at VCC = 5V  
- **Input/Output Compatibility:**  
  - 5V tolerant inputs  
  - 3.3V/5V compatible outputs  
- **Package Type:** VSSOP (Very Small Outline Package)  
- **Pin Count:** 20  

### **Descriptions:**
- The TC74VHCV245FK is an octal bus transceiver with 3-state outputs, designed for bidirectional communication between data buses.  
- It features two separate supply rails (VCC and GND) and direction control (DIR) for data flow management.  
- The output enable (OE) pin allows the outputs to be placed in a high-impedance state.  

### **Features:**
1. **Wide Operating Voltage Range:** Supports 2.0V to 5.5V, making it suitable for mixed-voltage systems.  
2. **High-Speed CMOS Technology:** Provides fast switching speeds with low power consumption.  
3. **Bidirectional Data Flow:** Controlled by the DIR input pin.  
4. **3-State Outputs:** Allows bus isolation when OE is high.  
5. **5V-Tolerant Inputs:** Ensures compatibility with 5V logic levels even when operating at 3.3V.  
6. **Low Noise:** Features balanced propagation delays to minimize noise.  
7. **ESD Protection:** Includes built-in protection against electrostatic discharge.  

This information is based solely on Toshiba's official documentation for the TC74VHCV245FK.

Application Scenarios & Design Considerations

Octal Schmitt Bus Transceiver

Alternative Part Number

  • SN74LVC245APW --: Octal bus transceiver in TSSOP-20 with 5V-tolerant inputs, functionally equivalent to the VHCV245 and widely available.
  • 74LVC245APW --: Low-voltage octal transceiver in TSSOP-20, pin-compatible replacement with similar drive and voltage range.
  • MC74VHC245DTR2G --: VHC-series octal bus transceiver in TSSOP-20, same logic family behavior and pinout as the original.
