CD74HC4511EE4 datasheet by Texas Instruments

CD74HC4511EE4 Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC4511EE4?
  The maximum frequency of operation for the CD74HC4511EE4 is 40 MHz, but it can vary depending on the operating voltage and load capacitance.
• How do I ensure proper power sequencing when using the CD74HC4511EE4?
  To ensure proper power sequencing, the VCC pin should be powered up before the input signals, and the input signals should be stable before the clock signal is applied.
• What is the recommended operating voltage range for the CD74HC4511EE4?
  The recommended operating voltage range for the CD74HC4511EE4 is 2V to 6V, with a typical operating voltage of 5V.
• How do I handle unused inputs on the CD74HC4511EE4?
  Unused inputs on the CD74HC4511EE4 should be tied to a logic high or low level to prevent floating inputs, which can cause unpredictable behavior.
• What is the maximum output current that the CD74HC4511EE4 can sink or source?
  The maximum output current that the CD74HC4511EE4 can sink or source is 25 mA, but it's recommended to limit the output current to 10 mA or less to ensure reliable operation.
