CD74HCT4538E datasheet by Texas Instruments

CD74HCT4538E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HCT4538E?
  The maximum frequency of operation for the CD74HCT4538E is 30 MHz.
• Can I use the CD74HCT4538E in a 5V system?
  Yes, the CD74HCT4538E is compatible with 5V systems, but it's recommended to use a voltage regulator to ensure a stable 5V supply.
• How do I handle the enable inputs (EN1, EN2) for proper operation?
  The enable inputs (EN1, EN2) must be tied to a valid logic level (VCC or GND) to ensure proper operation. Leaving them floating can cause unpredictable behavior.
• What is the recommended termination for the outputs of the CD74HCT4538E?
  The outputs of the CD74HCT4538E should be terminated with a 10kΩ to 22kΩ pull-up resistor to ensure proper signal integrity.
• Can I use the CD74HCT4538E in a 3.3V system?
  Yes, the CD74HCT4538E is compatible with 3.3V systems, but the output voltage will be limited to 3.3V. Ensure that the system can tolerate the reduced output voltage.
