SN74AHC14DE4 datasheet by Texas Instruments

SN74AHC14DE4 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the SN74AHC14DE4?
  The recommended operating voltage range for the SN74AHC14DE4 is 2V to 5.5V, with a typical voltage of 3.3V or 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 SN74AHC14DE4?
  The maximum frequency of operation for the SN74AHC14DE4 is typically around 100 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 output load, such as a 1kΩ to 10kΩ resistor, and to keep the output traces short and well-terminated.
• Can I use the SN74AHC14DE4 in a 3.3V system with 5V tolerant inputs?
  Yes, the SN74AHC14DE4 is 5V tolerant, meaning it can accept input voltages up to 5.5V even when operating at a lower voltage such as 3.3V.
