Description and Introduction

Single Bus Buffer Gate With 3-State Output The SN74AHCT1G125DCKT is a single bus buffer gate manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Technology Family:** AHCT  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Input Type:** TTL-Compatible  
- **Output Type:** CMOS  
- **Number of Channels:** 1  
- **Output Current:** ±8mA  
- **Propagation Delay:** 7.5ns (typical) at 5V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** SC-70 (DCK), 5-pin  

### **Descriptions:**
- A single bus buffer gate with 3-state output.  
- Designed for voltage-level translation between TTL and CMOS logic levels.  
- Features an output enable (OE) input for high-impedance state control.  

### **Features:**
- **3-State Output:** Allows multiple outputs to be connected to a common bus.  
- **Low Power Consumption:** Typical ICC of 1µA.  
- **High Noise Immunity:** CMOS input levels with TTL compatibility.  
- **Wide Operating Voltage:** Supports 4.5V to 5.5V operation.  
- **ESD Protection:** Exceeds 2000V HBM per JESD 22.  

This information is based on TI's official datasheet for the SN74AHCT1G125DCKT.

Application Scenarios & Design Considerations

Single Bus Buffer Gate With 3-State Output

Alternative Part Number

  • NC7SZ125P5X --: Single-gate bus buffer with 3-state output in SC-70 package, functionally equivalent to the SN74AHCT1G125 and widely available.
  • 74AHCT1G125GW,125 --: Same AHCT logic family single buffer with 3-state output, TSSOP package, direct functional replacement with matching speed and drive.
  • MC74VHC1G125DFT1G --: Single non-inverting buffer with 3-state output in SC-70, similar CMOS logic function and pinout, suitable drop-in alternative.
  • MC74VHCT1G125DFT1G --: Single non-inverting 3-state buffer in VHCT family with TTL-compatible inputs; functionally equivalent to the AHCT1G125 and widely available in SC-70.
  • SN74LVC1G125DBVR --: Same single 3-state buffer function from the same vendor in a different logic family; LVC offers lower voltage operation and is a common cross-family substitute when AHCT is not critical.
