CD74HC4514E datasheet by Texas Instruments

CD74HC4514E Frequently Asked Questions (FAQs)

• What is the maximum frequency of the clock input?
  The maximum frequency of the clock input is 25 MHz, but it can vary depending on the operating voltage and temperature.
• How do I ensure that the device is properly powered up and initialized?
  To ensure proper power-up and initialization, make sure to follow the recommended power-up sequence, which is to apply VCC before applying any input signals. Also, ensure that the clock input is stable and within the recommended frequency range.
• What is the maximum capacitive load that the device can drive?
  The CD74HC4514E can drive up to 50 pF of capacitive load, but it's recommended to keep the load capacitance as low as possible to ensure reliable operation.
• How do I handle the asynchronous reset input (RST)?
  The asynchronous reset input (RST) should be asserted low to reset the device. When RST is low, all outputs are forced low, and the device is reset to its initial state. When RST is released, the device will resume normal operation.
• What is the recommended operating voltage range for the device?
  The recommended operating voltage range for the CD74HC4514E is 2.0 V to 6.0 V, with a typical operating voltage of 5.0 V.
