SN74HC03NE4 datasheet by Texas Instruments

SN74HC03NE4 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the SN74HC03NE4?
  The recommended operating voltage range for the SN74HC03NE4 is 2V to 6V, with a typical voltage of 5V.
• How do I handle the input pins when they are not in use?
  When the input pins are not in use, they should be tied to a valid logic level (either VCC or GND) to prevent them from floating and causing unintended behavior.
• What is the maximum frequency of operation for the SN74HC03NE4?
  The maximum frequency of operation for the SN74HC03NE4 is typically around 25 MHz, but this can vary depending on the specific application and operating conditions.
• How do I ensure that the output pins can drive the required load current?
  The output pins of the SN74HC03NE4 can drive a maximum current of 25 mA. To ensure that the output pins can drive the required load current, you should check the output current requirements of the load and ensure that the SN74HC03NE4 can provide the necessary current.
• What is the purpose of the internal pull-up resistors on the input pins?
  The internal pull-up resistors on the input pins are used to pull the input pins high when they are not driven by an external signal. This helps to prevent the input pins from floating and causing unintended behavior.
