Description and Introduction

Single Bus Buffer Gate With 3-State Output The SN74AHCT1G125DCKR is a single bus buffer gate with 3-state output, manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Logic Type:** Buffer/Driver  
- **Number of Channels:** 1  
- **Output Type:** 3-State  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **High-Level Input Voltage (Min):** 2V  
- **Low-Level Input Voltage (Max):** 0.8V  
- **Propagation Delay (Max):** 8.5 ns at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SC-70 (DCK), 5-Pin  

### **Features:**  
- **Wide Operating Voltage:** Supports 4.5V to 5.5V  
- **3-State Output:** Allows multiple outputs to be connected to a bus  
- **Low Power Consumption:** CMOS technology  
- **High Noise Immunity:** Typical of AHCT logic family  
- **Schmitt-Trigger Input:** Improves noise rejection  
- **ESD Protection:** Exceeds 2000V per JESD 22  

### **Applications:**  
- Bus buffering  
- Signal isolation  
- Level shifting  
- General-purpose logic  

This device is part of TI's AHCT logic family, designed for high-speed CMOS applications while maintaining TTL compatibility.

Application Scenarios & Design Considerations

Single Bus Buffer Gate With 3-State Output

Alternative Part Number

  • 74AHCT1G125GW,125 --: Same single buffer/line driver function with 3-state output in AHCT logic family, available in a small SOT package, direct functional equivalent to the TI device.
  • MC74VHCT1G125DFT1G --: Single non-inverting buffer with 3-state output in VHCT logic, TTL-compatible inputs and similar speed, suitable drop-in functional replacement in SC-70 package.
  • SN74LVC1G125DBVR --: Same single 3-state buffer function from the same vendor in a comparable SOT-23 package; LVC family offers similar drive and speed, though input thresholds differ slightly from AHCT.
