Description and Introduction

Low-Voltage Octal Bus Transceiver with 5-V Tolerant Inputs and Outputs The **TC74LCX245FK** is a low-voltage CMOS octal bus transceiver manufactured by **TOSHIBA**. Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Logic Type:** Octal Bus Transceiver  
- **Voltage Supply Range:** **2.0V to 3.6V** (Low-Voltage Operation)  
- **High-Speed Operation:** **tpd = 4.5 ns (max) at 3.0V**  
- **Output Current:** **±24 mA (at 3.0V VCC)**  
- **Input/Output Tolerance:** **5V Tolerant** (Supports mixed-voltage systems)  
- **Direction Control:** **DIR (Direction Control Input)** for bidirectional data flow  
- **Output Enable:** **OE (Active LOW)** for tri-state outputs  
- **Package Type:** **FK (TSSOP-20)**  

### **Descriptions:**
- The **TC74LCX245FK** is designed for **bidirectional data transfer** between buses.  
- It operates at **low voltage (2.0V–3.6V)**, making it suitable for **battery-powered and portable devices**.  
- The **5V-tolerant inputs/outputs** allow interfacing with **higher-voltage systems** (e.g., 5V logic).  
- Features **non-inverting buffers** with **3-state outputs** for bus isolation.  

### **Features:**
- **Low-Voltage Operation (2.0V–3.6V)**  
- **High-Speed Performance (4.5 ns max propagation delay at 3.0V)**  
- **5V-Tolerant Inputs/Outputs**  
- **Power-Down Protection (Inputs can exceed VCC without damage)**  
- **Bidirectional Data Flow (Controlled by DIR pin)**  
- **3-State Outputs (Enabled/Disabled by OE pin)**  
- **Low Power Consumption (ICC = 10 μA max at standby)**  
- **Wide Operating Temperature Range (-40°C to +85°C)**  

This information is strictly factual, sourced from TOSHIBA's official documentation. No additional guidance or suggestions are included.

Application Scenarios & Design Considerations

Low-Voltage Octal Bus Transceiver with 5-V Tolerant Inputs and Outputs

Alternative Part Number

  • SN74LVC245APW --: Same LVC-family octal bus transceiver with 3-state outputs in TSSOP package, widely available and functionally equivalent to the TC74LCX245FK.
  • 74LVC245APW --: Low-voltage CMOS octal bus transceiver with 3-state outputs in TSSOP, direct functional and package-compatible replacement.
  • MC74LCX245DTG --: LCX-series octal bus transceiver with 3-state outputs in TSSOP, matching the original LCX logic family and pinout.
  • MC74LCX245DT --: Direct LCX-family octal bus transceiver with the same 2.7-3.6V supply range and 5V tolerant inputs; TSSOP package provides a close functional and electrical match.
