CD4067BF datasheet by Texas Instruments

CD4067BF Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD4067BF?
  The CD4067BF can operate up to 5 MHz, but the maximum frequency of operation depends on the specific application and the quality of the signal being switched.
• How do I ensure that the CD4067BF switches correctly and doesn't get stuck in an intermediate state?
  To ensure correct switching, make sure to use a clean and stable clock signal, and ensure that the voltage supply is within the recommended range. Also, use a pull-up or pull-down resistor on the enable input to prevent intermediate states.
• What is the maximum current that the CD4067BF can handle?
  The CD4067BF can handle up to 25mA of current per channel, but it's recommended to keep the current below 10mA to ensure reliable operation and to prevent overheating.
• Can I use the CD4067BF as a level shifter?
  Yes, the CD4067BF can be used as a level shifter, but it's not recommended as it's not designed for that purpose. The CD4067BF is primarily a analog multiplexer/demultiplexer, and using it as a level shifter may affect its performance and reliability.
• How do I reduce the power consumption of the CD4067BF?
  To reduce power consumption, use a lower voltage supply, reduce the clock frequency, and use a lower current output. You can also consider using a lower power version of the CD4067BF, such as the CD4067B.
