  • Logic level inversion

The SN74HC04N from Texas Instruments contains six independent inverter gates in a 14-PDIP package. Each inverter performs the NOT function: a HIGH input produces a LOW output and vice versa. The 74HC04N is the standard (non-Schmitt) version, with switching thresholds at approximately 50% of VCC. It is pin-compatible with the 74HC14N Schmitt-trigger inverter, allowing easy substitution when hysteresis is needed. The 9ns propagation delay at 4.5V supports moderate-speed digital applications. Two inverters in series form a non-inverting buffer; an odd number of inverters with feedback forms a ring oscillator. The 74HC04 is commonly used with a crystal and feedback resistor to build a Pierce oscillator for microcontroller clock generation.

Each inverter in the 74HC04N uses a CMOS push-pull output stage with complementary N-channel and P-channel MOSFETs. When the input is HIGH, the N-channel transistor turns on and the P-channel turns off, pulling the output LOW. When the input is LOW, the P-channel turns on and the N-channel turns off, pulling the output HIGH. The input switching threshold is approximately 50% of VCC. For crystal oscillator applications, the Pierce configuration uses one inverter as the gain element, with the crystal providing feedback between input and output, and capacitors to ground on both sides setting the load capacitance. A feedback resistor (1-10MOhm) biases the inverter into its linear region for oscillator startup.
