CD74ACT86MDREP Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for CD74ACT86MDREP?
  The recommended operating voltage range for CD74ACT86MDREP is 4.5V to 5.5V, although it can operate from 2V to 6V with reduced performance.
• How do I handle the output enable (OE) pin in my design?
  The output enable (OE) pin is active-low, meaning it should be connected to GND to enable the outputs. When OE is high, the outputs are in a high-impedance state.
• What is the propagation delay for the CD74ACT86MDREP?
  The typical propagation delay for the CD74ACT86MDREP is around 10ns to 15ns, depending on the operating voltage and temperature.
• Can I use the CD74ACT86MDREP in a 3.3V system?
  Yes, the CD74ACT86MDREP 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 the specified propagation delay and rise/fall times.
• How do I ensure proper power sequencing when using the CD74ACT86MDREP?
  To ensure proper power sequencing, the VCC pin should be powered up before the input signals, and the input signals should be stable before the output enable (OE) pin is asserted low.
