Description and Introduction

Single Bus Buffer Gate With 3-State Outputs The SN74AHC1G126DCKR is a single bus buffer gate with 3-state output, manufactured by Texas Instruments.  

### **Specifications:**  
- **Technology Family:** AHC  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **Number of Channels:** 1  
- **Output Type:** 3-State  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SC-70 (DCK), 5-pin  
- **Input Type:** CMOS  
- **Propagation Delay:** 6.5 ns (typical) at 5 V  
- **High-Level Output Current:** -8 mA  
- **Low-Level Output Current:** 8 mA  
- **ESD Protection:** > 2000 V (HBM)  

### **Descriptions:**  
- A single-channel non-inverting buffer with 3-state output control.  
- Designed for bus-oriented applications where multiple devices share a common bus.  
- Supports partial power-down mode with proper interface protection.  

### **Features:**  
- **Wide Operating Voltage Range:** 2 V to 5.5 V  
- **Balanced Propagation Delays:** Optimized for signal integrity.  
- **Low Power Consumption:** CMOS technology ensures minimal power usage.  
- **3-State Output:** Allows high-impedance state for bus isolation.  
- **Latch-Up Performance Exceeds 250 mA per JESD 17.**  
- **Schmitt-Trigger Inputs:** Improves noise immunity.

Application Scenarios & Design Considerations

Single Bus Buffer Gate With 3-State Outputs

Alternative Part Number

  • 74AHC1G126GW,125 --: Single buffer/line driver with 3-state output in the same AHC logic family, offered in a small SOT-353 package; functionally equivalent to the original with comparable drive and speed.
  • MC74VHC1G126DFT1G --: Single non-inverting 3-state buffer from the VHC family, pin-compatible in function and suitable as a direct logic-level replacement in most designs.
  • TC7SH126FU --: Single 3-state bus buffer in the SH series with similar voltage range and drive capability, usable as an alternative where package and pinout allow.
