Description and Introduction

Quadruple Bus Buffer Gates With 3-State Outputs The SN74AHCT126D is a quad bus buffer gate manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Buffer/Driver  
- **Number of Channels:** 4  
- **Output Type:** 3-State  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **High-Level Input Voltage (VIH):** 2V (min)  
- **Low-Level Input Voltage (VIL):** 0.8V (max)  
- **High-Level Output Current (IOH):** -8mA  
- **Low-Level Output Current (IOL):** 8mA  
- **Propagation Delay Time (tpd):** 7.5ns (max) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-14  

### **Descriptions:**  
The SN74AHCT126D is a high-speed CMOS logic device with 3-state outputs. It is designed for bus-oriented applications, allowing multiple outputs to be connected to a common bus without interference.  

### **Features:**  
- **3-State Outputs:** Allows multiple devices to share a common bus.  
- **High Drive Outputs:** Supports up to 8mA output current.  
- **Wide Operating Voltage:** Compatible with 5V systems.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **Balanced Propagation Delays:** Ensures consistent signal timing.  
- **ESD Protection:** Exceeds 2000V per JESD 22-A114.  

This information is based on the manufacturer's datasheet and specifications.

Application Scenarios & Design Considerations

Quadruple Bus Buffer Gates With 3-State Outputs

Alternative Part Number

  • MC74VHCT126ADG --: Quad buffer with 3-state outputs in the same VHCT logic family, SOIC-14 package, direct functional and pin-compatible replacement.
  • 74AHCT126PW,118 --: Equivalent AHCT quad 3-state buffer from a different vendor, TSSOP-14 package, same logic function and voltage range.
  • SN74AHCT125DR --: Same AHCT family quad 3-state buffer with active-low enables; usable when enable polarity can be inverted in the design.
