Description and Introduction

OCTAL BUS TRANSCEIVER The TC74VHC245FT is a high-speed CMOS octal bus transceiver 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)  
- **Type:** Octal Bus Transceiver  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **High-Speed Operation:** tpd = 4.3 ns (max) at 5V  
- **Low Power Consumption:** ICC = 4 μA (max) at Ta = 25°C  
- **Output Drive Capability:** ±8 mA at 3.0V, ±24 mA at 5.5V  
- **Input Voltage Levels:** CMOS-compatible (TTL compatible at 3.3V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** TSSOP-20  

### **Descriptions:**  
- The TC74VHC245FT is an 8-bit bidirectional transceiver with 3-state outputs.  
- It features two DIR (direction control) inputs to determine data flow (A to B or B to A).  
- The OE (output enable) pin controls the outputs, allowing bus isolation when disabled.  
- Designed for high-speed data transfer while maintaining low power consumption.  

### **Features:**  
- **Bidirectional Data Flow:** Controlled by DIR input.  
- **3-State Outputs:** Allows bus isolation when OE is high.  
- **Wide Operating Voltage:** Supports 2.0V to 5.5V, making it versatile for mixed-voltage systems.  
- **Balanced Propagation Delays:** Ensures reliable high-speed operation.  
- **ESD Protection:** Exceeds 2000V (HBM) for improved reliability.  
- **Pin-Compatible:** With 74-series logic devices.  

This information is based solely on the manufacturer's datasheet and does not include any additional recommendations or usage guidance.

Application Scenarios & Design Considerations

OCTAL BUS TRANSCEIVER

Alternative Part Number

  • SN74AHC245PW --: Octal bus transceiver with 3-state outputs in TSSOP, same AHC logic family and pinout, widely available and directly interchangeable.
  • 74AHC245PW --: Equivalent AHC octal bus transceiver in TSSOP package with matching function and pinout, good second-source option.
  • MC74VHC245DT --: VHC-family octal bus transceiver in TSSOP with comparable speed and drive, suitable functional replacement.
  • SN74AHC245PWR --: Octal bus transceiver with 3-state outputs in the same AHC logic family, widely available and pin-compatible in function.
  • MC74VHC245DTR2G --: VHC-family octal bus transceiver matching the original VHC logic characteristics, suitable drop-in functional alternative.
  • 74VHC245MTC --: Same VHC octal transceiver function in TSSOP package, compatible voltage range and 3-state outputs for bus interface use.
