SN74HC04DBRE4 datasheet by Texas Instruments

SN74HC04DBRE4 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the SN74HC04DBRE4?
  The recommended operating voltage range for the SN74HC04DBRE4 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, it is recommended to tie them to VCC or GND through a pull-up or pull-down resistor to prevent floating inputs and reduce power consumption.
• What is the maximum frequency of operation for the SN74HC04DBRE4?
  The maximum frequency of operation for the SN74HC04DBRE4 is typically around 25 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure that the output signals are not distorted or attenuated?
  To ensure that the output signals are not distorted or attenuated, it is recommended to use a suitable load impedance and to keep the output traces short and well-terminated to minimize signal reflections and ringing.
• Can I use the SN74HC04DBRE4 in a 3.3V system?
  Yes, the SN74HC04DBRE4 can be used in a 3.3V system, but the output voltage levels may not be as high as those in a 5V system, and the noise margin may be reduced.
