CD74AC151E datasheet by Texas Instruments

CD74AC151E Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD74AC151E can handle?
  The CD74AC151E can handle clock frequencies up to 100 MHz.
• How do I ensure that the CD74AC151E is properly powered?
  The CD74AC151E requires a power supply voltage (VCC) of 2.0V to 6.0V, and it is recommended to use a decoupling capacitor of 0.1uF to 1uF between VCC and GND to ensure proper power supply noise reduction.
• What is the propagation delay of the CD74AC151E?
  The propagation delay of the CD74AC151E is typically around 10ns to 15ns, depending on the operating frequency and voltage.
• Can I use the CD74AC151E in a 3.3V system?
  Yes, the CD74AC151E is compatible with 3.3V systems, but it is recommended to use a voltage regulator to ensure a stable 3.3V supply voltage.
• How do I handle the output enable (OE) pin?
  The output enable (OE) pin is active-low, meaning that the outputs are enabled when OE is low (0V) and disabled when OE is high (VCC). It is recommended to tie OE to GND or VCC depending on the application requirements.
