- **Mounting Type:** Surface Mount  

### **Descriptions:**  
- The SN74HCT02DR is a high-speed CMOS logic device with four independent 2-input NOR gates.  
- It is compatible with TTL levels, making it suitable for interfacing between TTL and CMOS systems.  
- The device operates with a wide supply voltage range and provides balanced propagation delays.  

### **Features:**  
- **Wide Operating Voltage Range:** 4.5V to 5.5V  
- **Low Power Consumption:** Typical ICC of 1µA  
- **High Noise Immunity:** CMOS technology ensures reliable operation in noisy environments  
- **Balanced Propagation Delays:** Ensures consistent timing performance  
- **TTL-Compatible Inputs:** Can be driven by TTL outputs  
- **ESD Protection:** Exceeds 2000V per JESD 22  

This information is based on the manufacturer's datasheet and technical documentation.
