CD4002BE datasheet by Texas Instruments

CD4002BE Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the CD4002BE?
  The CD4002BE can operate up to 10 MHz, but the actual frequency limit depends on the specific application and the quality of the clock signal.
• How do I ensure the CD4002BE is properly powered?
  The CD4002BE requires a single 5V power supply, and it's essential to decouple the power pins with 0.1uF capacitors to ensure stable operation.
• What is the maximum current that the CD4002BE can sink or source?
  The CD4002BE can sink or source up to 1.5mA per output, but it's recommended to limit the current to 1mA or less to ensure reliable operation.
• How do I handle the unused inputs on the CD4002BE?
  Unused inputs should be tied to a valid logic level (either VCC or GND) to prevent floating inputs, which can cause unpredictable behavior.
• Is the CD4002BE suitable for use in high-temperature environments?
  The CD4002BE is rated for operation up to 125°C, but it's essential to consider the specific application and potential thermal issues, such as thermal runaway or reduced lifespan.
