Description and Introduction

Low-Voltage Octal Bus Buffer with 3.6 V Tolerant Inputs and Outputs The TC7MA244FK is a buffer and line driver integrated circuit (IC) manufactured by Toshiba. Below are its specifications, descriptions, and features based on available factual information:

### **Manufacturer:**  
Toshiba  

### **Part Number:**  
TC7MA244FK  

### **Description:**  
The TC7MA244FK is a dual-supply voltage level translator and buffer IC designed for bidirectional voltage translation between different logic levels. It is commonly used in applications requiring interfacing between devices operating at different voltage levels.  

### **Key Features:**  
1. **Bidirectional Voltage Translation:** Supports voltage level shifting between two different logic levels.  
2. **Dual-Supply Operation:** Operates with two separate voltage supplies (VCCA and VCCB) for translation.  
3. **Wide Voltage Range:**  
   - VCCA: 1.2V to 3.6V  
   - VCCB: 1.65V to 5.5V  
4. **High-Speed Operation:** Supports fast signal transmission with minimal propagation delay.  
5. **Low Power Consumption:** Designed for energy-efficient applications.  
6. **ESD Protection:** Provides electrostatic discharge (ESD) protection for improved reliability.  
7. **Package Type:** Available in a small surface-mount package (e.g., TSSOP, VSSOP).  

### **Applications:**  
- Voltage level translation in mixed-voltage systems  
- Communication interfaces (I2C, SPI, UART)  
- Microcontroller and FPGA interfacing  
- Portable and battery-powered devices  

### **Additional Specifications:**  
- **Number of Channels:** Typically 4 or 8 (varies by variant)  
- **Logic Family:** CMOS  
- **Operating Temperature Range:** -40°C to +85°C (industrial grade)  

For exact pin configurations, electrical characteristics, and detailed datasheet information, refer to Toshiba’s official documentation.

Application Scenarios & Design Considerations

Alternative Part Number

  • SN74LVC244APW --: Octal buffer/line driver with 3-state outputs in TSSOP, functionally equivalent to the TC7MA244FK and widely available.
  • 74LVC244APW --: Low-voltage CMOS octal buffer/line driver in TSSOP package, direct functional replacement with similar drive and speed.
  • MC74LCX244DT --: Low-voltage octal buffer/line driver with 3-state outputs in TSSOP, suitable drop-in alternative for the TC7MA244FK.
  • SN74AHC244PWR --: Widely available octal buffer/line driver with similar function and drive strength, pin-compatible in many designs, and easy to source.
  • MC74VHC244DTR2G --: VHC-family octal buffer with comparable speed and low power, good drop-in candidate for the Toshiba VHC-type device.
  • 74AHC244PW,118 --: AHC octal buffer offering similar electrical characteristics and broad availability as a functional replacement.
