CD54AC74F3A datasheet by Texas Instruments

CD54AC74F3A Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for CD54AC74F3A?
  The recommended operating voltage range for CD54AC74F3A is 4.5V to 5.5V, although it can operate from 3V to 6V with reduced performance.
• How do I handle the output enable (OE) pin?
  The output enable (OE) pin should be connected to GND or VCC, depending on the desired output state. Leaving it unconnected can cause unpredictable behavior.
• What is the maximum clock frequency for CD54AC74F3A?
  The maximum clock frequency for CD54AC74F3A is 25 MHz, but it can operate up to 30 MHz with reduced performance and increased power consumption.
• Can I use CD54AC74F3A in a 3.3V system?
  Yes, CD54AC74F3A can operate in a 3.3V system, but the output voltage levels may not be compatible with 3.3V logic. Use a voltage translator or level shifter if necessary.
• How do I ensure reliable operation at high temperatures?
  To ensure reliable operation at high temperatures, ensure proper heat dissipation, use a heat sink if necessary, and follow the recommended operating conditions and thermal guidelines.
