The maximum operating frequency of the 74HC03D is typically around 25 MHz, but it can vary depending on the specific application and operating conditions.
To ensure proper output voltage swing, it's recommended to use a pull-up resistor (e.g., 1 kΩ) to VCC and a pull-down resistor (e.g., 1 kΩ) to GND for each output pin.
Yes, the 74HC03D can be used as a level shifter, but it's essential to ensure that the input voltage levels are within the recommended range (VCC - 1.5V to VCC + 0.5V) to maintain proper logic levels.
A simple POR circuit can be implemented using a capacitor (e.g., 10 μF) connected between VCC and GND, with a resistor (e.g., 1 kΩ) in series with the capacitor to limit the inrush current.
To minimize power consumption, ensure that all unused inputs are tied to a valid logic level (either VCC or GND), and consider using a lower VCC voltage (e.g., 3.3V) if possible.
