CD74HC4511E datasheet by Texas Instruments

CD74HC4511E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC4511E?
  The maximum frequency of operation for the CD74HC4511E is 25 MHz.
• How do I ensure that the CD74HC4511E is properly powered?
  To ensure proper operation, the CD74HC4511E requires a stable power supply voltage between 2V and 6V, with a recommended operating voltage of 5V. Additionally, decoupling capacitors should be used to filter out noise and ensure stable operation.
• What is the maximum current that the CD74HC4511E can sink or source?
  The CD74HC4511E can sink or source up to 25mA of current per output pin.
• How do I handle the asynchronous reset input (RST) on the CD74HC4511E?
  The asynchronous reset input (RST) should be tied to VCC through a pull-up resistor (typically 1kΩ) to ensure that the device is properly reset. A low-going pulse on the RST input will reset the device.
• What is the propagation delay time for the CD74HC4511E?
  The propagation delay time for the CD74HC4511E is typically around 10ns to 20ns, depending on the operating voltage and temperature.
