CD4011AD3 datasheet by Texas Instruments

CD4011AD3 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the CD4011AD3?
  The recommended operating voltage range for the CD4011AD3 is 3V to 15V, although it can operate as low as 2V with reduced performance.
• How do I handle unused inputs on the CD4011AD3?
  Unused inputs on the CD4011AD3 should be tied to a logic level (either VCC or GND) to prevent floating inputs and ensure proper operation.
• What is the maximum frequency of operation for the CD4011AD3?
  The maximum frequency of operation for the CD4011AD3 is typically around 10 MHz, although this can vary depending on the specific application and operating conditions.
• Can I use the CD4011AD3 in a 5V system?
  Yes, the CD4011AD3 can be used in a 5V system, and it is a popular choice for many 5V logic circuits due to its low power consumption and high noise immunity.
• How do I ensure proper noise immunity when using the CD4011AD3?
  To ensure proper noise immunity when using the CD4011AD3, use a decoupling capacitor (typically 0.1 uF) between VCC and GND, and keep the device away from high-noise sources such as motors or relays.
