HEF4081BP datasheet by Philips Semiconductors

HEF4081BP Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the HEF4081BP?
  The maximum operating frequency of the HEF4081BP is typically around 10 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure that the HEF4081BP is properly powered?
  The HEF4081BP requires a single power supply voltage (VDD) between 3V and 15V, with a recommended operating voltage of 5V. Ensure that the power supply is stable and decoupled with capacitors to prevent noise and oscillations.
• What is the input voltage threshold for the HEF4081BP?
  The input voltage threshold for the HEF4081BP is typically around 2.5V for a logic high and 0.5V for a logic low, but it can vary depending on the specific application and operating conditions.
• Can I use the HEF4081BP in a high-temperature environment?
  The HEF4081BP is rated for operation up to 70°C, but it can be derated for higher temperatures. Consult the datasheet and application notes for specific guidance on high-temperature operation.
• How do I handle unused inputs on the HEF4081BP?
  Unused inputs on the HEF4081BP should be tied to a valid logic level (either VDD or GND) to prevent floating inputs and ensure proper operation.
