SN74HC03DR datasheet by Texas Instruments

SN74HC03DR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74HC03DR?
  The maximum operating frequency of the SN74HC03DR is 25 MHz.
• Can I use the SN74HC03DR in a 5V system?
  Yes, the SN74HC03DR is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply.
• How do I handle the output enable (OE) pin?
  The output enable (OE) pin is active-low, meaning it should be connected to GND to enable the output. Leaving it unconnected or connecting it to VCC will disable the output.
• What is the propagation delay of the SN74HC03DR?
  The propagation delay of the SN74HC03DR is typically around 10-15 ns, but it can vary depending on the operating frequency and load conditions.
• Can I use the SN74HC03DR in a 3.3V system?
  Yes, the SN74HC03DR is compatible with 3.3V systems, but the output voltage will be limited to 3.3V. Ensure that the input signals are also 3.3V-compatible.
