CD74HCT597E datasheet by Texas Instruments

CD74HCT597E Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for CD74HCT597E?
  The recommended operating voltage range for CD74HCT597E is 4.5V to 5.5V, although it can operate down to 3V with reduced performance.
• How do I handle the asynchronous reset input (MR) in CD74HCT597E?
  The asynchronous reset input (MR) should be tied to VCC through a pull-up resistor (e.g., 1kΩ) to ensure proper operation. A low signal on MR resets the counter.
• Can I use CD74HCT597E in a 3.3V system?
  Yes, CD74HCT597E can operate at 3.3V, but the output voltage levels may not be fully compatible with 3.3V logic. Use a voltage translator or level shifter if necessary.
• How do I ensure proper power sequencing when using CD74HCT597E?
  Power up the VCC pin before applying any input signals, and ensure that the power supply is stable before enabling the clock input.
• What is the maximum clock frequency supported by CD74HCT597E?
  The maximum clock frequency supported by CD74HCT597E is 30 MHz, but this may vary depending on the specific application and operating conditions.
