CD74HCT688M Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the CD74HCT688M is 4.5V to 5.5V.
  • To ensure proper power supply, connect VCC to a stable 5V power source and GND to a reliable ground connection. Decouple the power supply with a 0.1uF capacitor to reduce noise.
  • The CD74HCT688M can handle clock frequencies up to 30 MHz.
  • The output enable (OE) pin is active-low, meaning that the outputs are enabled when OE is low (connected to GND) and disabled when OE is high (connected to VCC).
  • The propagation delay time for the CD74HCT688M is typically around 10-15 ns, but this can vary depending on the specific application and operating conditions.
