CD74HCT75E datasheet by Texas Instruments

CD74HCT75E Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD74HCT75E can handle?
  The CD74HCT75E can handle clock frequencies up to 30 MHz, but it's recommended to check the timing specifications in the datasheet for specific frequency ranges and operating conditions.
• How do I ensure that the CD74HCT75E is properly powered and decoupled?
  To ensure proper power and decoupling, connect VCC to a 5V power supply, and decouple the power pins with 0.1uF ceramic capacitors. Additionally, use a 10uF electrolytic capacitor for bulk decoupling.
• What is the recommended operating temperature range for the CD74HCT75E?
  The recommended operating temperature range for the CD74HCT75E is -40°C to 125°C. However, it's essential to check the datasheet for specific temperature-related specifications and derating factors.
• Can I use the CD74HCT75E in a 3.3V system?
  No, the CD74HCT75E is a 5V device and is not compatible with 3.3V systems. Using it in a 3.3V system may result in incorrect operation or damage to the device.
• How do I handle the asynchronous reset input (MR) in the CD74HCT75E?
  The asynchronous reset input (MR) should be tied to VCC through a pull-up resistor (e.g., 1kΩ) to ensure proper operation. This input should not be left floating, as it may cause unpredictable behavior.
