74AHCT138D,112 datasheet by NXP Semiconductors

74AHCT138D,112 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the 74AHCT138D,112?
  The maximum operating frequency of the 74AHCT138D,112 is 100 MHz.
• Can I use the 74AHCT138D,112 in a 5V system?
  Yes, the 74AHCT138D,112 is a 5V tolerant device, but it is recommended to use it in a 3.3V system for optimal performance.
• How do I handle the enable inputs (E1, E2, E3) when not in use?
  When not in use, the enable inputs (E1, E2, E3) should be tied to VCC or GND to prevent floating inputs and ensure proper device operation.
• What is the propagation delay of the 74AHCT138D,112?
  The propagation delay of the 74AHCT138D,112 is typically around 10-15 ns, but it can vary depending on the operating conditions and load capacitance.
• Can I use the 74AHCT138D,112 as a level translator?
  Yes, the 74AHCT138D,112 can be used as a level translator, but it is not recommended as it is not designed for this purpose. Instead, use a dedicated level translator device for optimal performance and reliability.
