SN74HC00DRE4 datasheet by Texas Instruments

SN74HC00DRE4 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74HC00DRE4?
  The maximum operating frequency of the SN74HC00DRE4 is typically 100 MHz, but it can vary depending on the application and operating conditions.
• How do I ensure the SN74HC00DRE4 is properly powered?
  The SN74HC00DRE4 requires a single power supply voltage (VCC) of 2.0 V to 6.0 V, and it's recommended to use a decoupling capacitor of 0.1 μF to 1 μF between VCC and GND to ensure proper operation.
• What is the input voltage threshold for the SN74HC00DRE4?
  The input voltage threshold for the SN74HC00DRE4 is typically 0.8 VCC for a logic high and 0.2 VCC for a logic low, but it's recommended to use a voltage level of at least 2.4 V for a logic high and no more than 0.4 V for a logic low to ensure reliable operation.
• How do I handle the output current of the SN74HC00DRE4?
  The SN74HC00DRE4 can sink or source up to 25 mA of current per output, but it's recommended to limit the output current to 10 mA or less to ensure reliable operation and prevent overheating.
• What is the propagation delay of the SN74HC00DRE4?
  The propagation delay of the SN74HC00DRE4 is typically around 10 ns to 20 ns, depending on the operating frequency and temperature.
