Additional Details:

The HD74HC09P is typically packaged in a 14-pin DIP (Dual In-line Package). It requires a supply voltage within the specified range (typically 2V to 6V). The value of the external pull-up resistor depends on the operating voltage and desired speed. Consult the Renesas datasheet for specific values and detailed timing diagrams. Ensure that the pull-up resistor is properly sized to guarantee correct logic levels.
