Description and Introduction

Low-Voltage Quad Bus Buffer with 5-V Tolerant Inputs and Outputs The TC74LCX126FT is a quad bus buffer gate manufactured by Toshiba. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Manufacturer:** TOSHIBA  
### **Part Number:** TC74LCX126FT  

### **Specifications:**  
- **Logic Type:** Quad Bus Buffer Gate with 3-State Output  
- **Number of Channels:** 4  
- **Supply Voltage Range (VCC):** 2.0V to 3.6V  
- **High-Level Input Voltage (VIH):** 2.0V (min) at VCC = 2.7V to 3.6V  
- **Low-Level Input Voltage (VIL):** 0.8V (max) at VCC = 2.7V to 3.6V  
- **High-Level Output Voltage (VOH):** 2.2V (min) at VCC = 3.0V, IOH = -24mA  
- **Low-Level Output Voltage (VOL):** 0.55V (max) at VCC = 3.0V, IOL = 24mA  
- **Maximum Propagation Delay:** 4.5ns (typ) at VCC = 3.3V, TA = 25°C  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** TSSOP-14  

### **Descriptions:**  
- The TC74LCX126FT is a low-voltage CMOS logic device with four independent buffer gates.  
- It features 3-state outputs, allowing multiple devices to share a common bus without interference.  
- Designed for high-speed operation while maintaining low power consumption.  

### **Features:**  
- **Low-Voltage Operation:** Supports 2.0V to 3.6V power supply.  
- **High-Speed Performance:** tpd = 4.5ns (max) at VCC = 3.3V.  
- **3-State Outputs:** Allows bus-oriented applications.  
- **Power-Down Protection:** Inputs and outputs include circuitry to prevent damage when VCC = 0V.  
- **TTL-Compatible Inputs:** Can interface with 5V TTL logic levels.  
- **Low Power Consumption:** ICC = 10μA (max) at TA = 25°C.  

This information is strictly based on the manufacturer's datasheet. No additional suggestions or guidance are included.

Application Scenarios & Design Considerations

Low-Voltage Quad Bus Buffer with 5-V Tolerant Inputs and Outputs

Alternative Part Number

  • SN74LVC126APWR --: Quad bus buffer gate with 3-state outputs in TSSOP-14, same LCX/LVC logic family function and pinout, widely available and directly drop-in compatible.
  • MC74LCX126DTR2G --: Quad 3-state buffer in TSSOP-14 with LCX technology, functionally equivalent to the TC74LCX126FT and suitable for 3.3V systems.
  • 74LVC126APW --: Quad buffer/line driver with 3-state outputs in TSSOP-14, LVC family offers comparable speed and drive, good second-source option.
  • SN74LVC126APW --: Quad bus buffer gate with 3-state outputs in the same LVC logic family, TSSOP package, pin-compatible and widely available.
  • MC74LCX126DT --: Direct LCX-family quad 3-state buffer alternative with comparable speed and drive, available in TSSOP.
  • 74LCX126MTCX --: Same LCX-family quad bus buffer with 3-state outputs in TSSOP, functionally equivalent to the TC74LCX126FT.
  • MC74LCX126DTG --: LCX quad bus buffer with 3-state outputs, same logic function and voltage range, available in TSSOP package.
