SN74ACT14DBLE Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the SN74ACT14DBLE?
  The recommended operating voltage range for the SN74ACT14DBLE is 4.5V to 5.5V, although it can operate as low as 3.5V with reduced performance.
• 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 SN74ACT14DBLE?
  The maximum frequency of operation for the SN74ACT14DBLE is typically around 100 MHz, although this can vary depending on the specific application and operating conditions.
• How do I ensure reliable operation over the full temperature range?
  To ensure reliable operation over the full temperature range (-40°C to 85°C), it is recommended to follow proper PCB design and layout guidelines, use a stable power supply, and ensure that the device is operated within its recommended operating conditions.
• Can I use the SN74ACT14DBLE in a 3.3V system?
  Yes, the SN74ACT14DBLE can be used in a 3.3V system, but the output voltage will be limited to around 3.3V, and the device may not meet its full speed and drive capability. Additionally, the input voltage threshold may be affected, and the device may not be fully compatible with 3.3V logic levels.
