Description and Introduction

Quadruple 2-Input Positive-NOR Gates The SN74AHCT02DR is a quad 2-input positive-NOR gate manufactured by Texas Instruments. Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Category:** Logic - Gates and Inverters  
- **Series:** 74AHCT  
- **Package / Case:** SOIC-14  
- **Packaging:** Tape & Reel (TR)  
- **Logic Type:** NOR Gate  
- **Number of Circuits:** 4  
- **Number of Inputs:** 2 per gate  
- **Output Type:** Push-Pull  
- **Voltage - Supply:** 4.5V to 5.5V  
- **Operating Temperature:** -40°C to +85°C  
- **Mounting Type:** Surface Mount  
- **Propagation Delay Time:** 8.5 ns (typical) at 5V  
- **High-Level Output Current:** -8 mA  
- **Low-Level Output Current:** 8 mA  

### **Descriptions:**  
- The SN74AHCT02DR is a high-speed CMOS logic device with four independent 2-input NOR gates.  
- It operates with a supply voltage range of 4.5V to 5.5V, making it compatible with TTL levels.  
- The device is designed for high-noise-immunity applications and features balanced propagation delays.  

### **Features:**  
- **TTL-Compatible Inputs:** Can interface directly with TTL logic levels.  
- **Low Power Consumption:** CMOS technology ensures low static power dissipation.  
- **High Noise Immunity:** Improved noise margins compared to standard logic families.  
- **Wide Operating Voltage Range:** Supports 4.5V to 5.5V operation.  
- **Balanced Propagation Delays:** Ensures consistent timing performance.  
- **ESD Protection:** Exceeds 2000V per JESD 22-A114.

Application Scenarios & Design Considerations

Quadruple 2-Input Positive-NOR Gates

Alternative Part Number

  • 74AHCT02D --: Same quad 2-input NOR gate function in AHCT logic family with identical pinout and SOIC-14 package, direct functional drop-in from a different vendor.
  • MC74VHCT02ADR2G --: Quad 2-input NOR gate in VHCT logic with 5V-tolerant inputs, similar speed and drive, SOIC-14 package, suitable substitute with minor logic-family variation.
  • CD74HCT02M --: Quad 2-input NOR gate in HCT family from the same manufacturer, same pinout and SOIC-14 footprint, slightly slower but widely available and cost-effective.
