Additional Details

The HD74HC04 is available in various packages, including DIP (Dual In-line Package) and SOIC (Small Outline Integrated Circuit). Its operating temperature range is typically -40°C to +85°C. Each inverter within the HD74HC04 functions independently. The input impedance is very high, and the output impedance is relatively low. When designing with the HD74HC04, it's important to consider the capacitive loading on the outputs, as excessive capacitance can increase propagation delay times. Always consult the datasheet for the most accurate and up-to-date specifications.
