CD74HCT283E datasheet by Texas Instruments

CD74HCT283E Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD74HCT283E can handle?
  The CD74HCT283E 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 CD74HCT283E is properly powered and decoupled?
  To ensure proper power and decoupling, use a 5V power supply, decouple the VCC pin with a 0.1uF ceramic capacitor, and use a 10uF electrolytic capacitor for bulk decoupling. Also, ensure that the power supply is clean and free from noise.
• What is the maximum input voltage that the CD74HCT283E can tolerate?
  The CD74HCT283E has a maximum input voltage of 5.5V, which is the absolute maximum rating. However, it's recommended to keep the input voltage within the recommended operating range of 4.5V to 5.5V for reliable operation.
• Can I use the CD74HCT283E in a 3.3V system?
  No, the CD74HCT283E is a 5V device and is not compatible with 3.3V systems. Using it in a 3.3V system may result in unreliable operation or damage to the device.
• How do I handle the asynchronous reset input (MR) in the CD74HCT283E?
  The asynchronous reset input (MR) should be tied to VCC through a pull-up resistor (e.g., 1kΩ) to ensure that the device is properly reset. A low signal on the MR input will reset the device, and a high signal will allow normal operation.
