Description and Introduction

SINGLE BUS BUFFER GATE WITH 3-STATE OUTPUT **Manufacturer:** Texas Instruments (TI)  

**Part Number:** SN74AHC1G125DCK  

### **Specifications:**  
- **Technology Family:** AHC  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **Number of Channels:** 1  
- **Output Type:** 3-State  
- **High-Level Output Current:** -8 mA  
- **Low-Level Output Current:** 8 mA  
- **Propagation Delay Time:** 8.5 ns (max) at 5 V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package/Case:** SC-70 (DCK), 5-Pin  

### **Descriptions:**  
The SN74AHC1G125DCK is a single bus buffer gate with 3-state output. It is designed for 2-V to 5.5-V VCC operation and features high noise immunity. The output is disabled when the output-enable (OE) input is high.  

### **Features:**  
- **Low Power Consumption:** Optimized for battery-powered applications  
- **3-State Output:** Allows multiple outputs to be connected to a common bus  
- **Wide Operating Voltage:** Supports 2 V to 5.5 V  
- **High Drive Capability:** ±8 mA output drive at 5 V  
- **Schmitt-Trigger Inputs:** Allows for slow input transition and better noise rejection  
- **ESD Protection:** Exceeds JESD 22 standards (2000-V Human-Body Model)  
- **Small Package:** SC-70 (5-pin) for space-constrained designs  

This device is commonly used in signal buffering, level shifting, and bus interface applications.

Application Scenarios & Design Considerations

SINGLE BUS BUFFER GATE WITH 3-STATE OUTPUT

Alternative Part Number

  • 74AHC1G125GW --: Same single-gate AHC bus buffer with active-low output enable in a small SOT package; pin-compatible function and widely available.
  • MC74VHC1G125DFT1G --: VHC-family single buffer with 3-state output, functionally equivalent to the AHC1G125 and available in SC-70.
  • SN74LVC1G125DBVR --: LVC-family single bus buffer with 3-state output in SOT-23-5; same logic function with wider supply range and higher drive.
  • 74AHC1G125GW,125 --: Same single buffer/line driver with 3-state output in a TSSOP-5 package, functionally equivalent to the SN74AHC1G125 and widely available.
  • TC7SH125F --: Single bus buffer with 3-state output in SOT-353 (SMV), equivalent logic function and package for direct replacement.
