### **Descriptions:**
The SN74HCU04 is an unbuffered hex inverter, meaning it provides six independent NOT gates in a single package. Unlike buffered inverters, it has minimal propagation delay variations, making it suitable for applications requiring precise timing.
### **Features:**
- **Unbuffered Outputs:** Ensures minimal propagation delay differences.
- **Wide Operating Voltage Range (2V to 6V):** Compatible with TTL and CMOS logic levels.
- **Low Power Consumption:** Typical ICC of 1µA (static).
- **Balanced Propagation Delays:** Optimized for high-speed operation.
- **High Noise Immunity:** CMOS technology provides stable performance in noisy environments.
- **ESD Protection:** Exceeds 2000V per JESD 22.
This device is commonly used in oscillator circuits, signal inversion, and logic-level conversion applications.
