HEF4001BP datasheet by NXP Semiconductors

HEF4001BP Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the HEF4001BP?
  The maximum frequency of operation for the HEF4001BP is 10 MHz, but it can be operated at higher frequencies with reduced voltage and current.
• How do I ensure that the HEF4001BP is properly powered?
  To ensure proper power supply, connect VCC to a stable 5V power supply, and GND to a solid ground. Decouple the power supply with a 100nF capacitor.
• What is the maximum current that the HEF4001BP can sink or source?
  The HEF4001BP can sink or source up to 20mA per output pin, but it's recommended to limit the current to 10mA per pin for reliable operation.
• How do I handle the unused inputs of the HEF4001BP?
  Unused inputs should be connected to VCC or GND through a 1kΩ resistor to prevent floating inputs and ensure proper operation.
• Is the HEF4001BP suitable for use in high-temperature environments?
  The HEF4001BP is rated for operation up to 70°C, but it can be used in higher temperature environments with derated specifications. Consult the datasheet for more information.
