CD74HC4016E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC4016E?
  The maximum frequency of operation for the CD74HC4016E is 10 MHz, but it can vary depending on the specific application and operating conditions.
• How do I handle the enable pins (EN1 and EN2) when using the CD74HC4016E?
  The enable pins (EN1 and EN2) are active-low, meaning they must be pulled low to enable the corresponding analog switch. When not in use, they should be pulled high to disable the switch and reduce power consumption.
• What is the on-resistance of the CD74HC4016E analog switches?
  The on-resistance of the CD74HC4016E analog switches is typically around 50-60 ohms, but it can vary depending on the specific operating conditions and voltage levels.
• Can I use the CD74HC4016E with analog signals that exceed the VCC supply voltage?
  No, the CD74HC4016E is not designed to handle analog signals that exceed the VCC supply voltage. The analog signal voltage should be within the range of VCC to GND to ensure proper operation and prevent damage to the device.
• How do I ensure proper switching times when using the CD74HC4016E?
  To ensure proper switching times, the control signals (S0-S3) should be driven with a fast rise and fall time (typically <10 ns) and the enable pins (EN1 and EN2) should be driven with a fast rise time (typically <10 ns) and a slower fall time (typically >10 ns) to prevent shoot-through currents.
