74HC4067D,652 datasheet by NXP Semiconductors

74HC4067D,652 Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the 74HC4067D,652?
  The maximum frequency of operation for the 74HC4067D,652 is 10 MHz, but it can be limited by the capacitance of the analog signal and the impedance of the output pins.
• How do I ensure proper power sequencing when using the 74HC4067D,652?
  To ensure proper power sequencing, the VCC pin should be powered up before the analog signal, and the analog signal should be powered down before the VCC pin. This prevents damage to the device and ensures proper operation.
• What is the recommended operating voltage range for the 74HC4067D,652?
  The recommended operating voltage range for the 74HC4067D,652 is 2.0 V to 6.0 V, with a typical operating voltage of 5.0 V.
• How do I handle ESD protection when using the 74HC4067D,652?
  The 74HC4067D,652 has built-in ESD protection, but it's still recommended to use external ESD protection devices, such as TVS diodes, to protect the device from electrostatic discharge.
• What is the maximum analog signal voltage that can be applied to the 74HC4067D,652?
  The maximum analog signal voltage that can be applied to the 74HC4067D,652 is VCC + 0.5 V, but it's recommended to keep the analog signal voltage within the VCC range to ensure proper operation.
