CD54ACT573F3A datasheet by Texas Instruments

CD54ACT573F3A Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for CD54ACT573F3A?
  The recommended operating voltage range for CD54ACT573F3A is 4.5V to 5.5V, as specified in the datasheet. However, it's recommended to operate the device at a fixed voltage of 5V for optimal performance.
• How do I handle the power-up and power-down sequencing of the CD54ACT573F3A?
  It's recommended to power up the VCC pin before the input signals, and power down the VCC pin after the input signals. This ensures that the device is properly initialized and avoids any potential latch-up or damage.
• What is the maximum frequency of operation for the CD54ACT573F3A?
  The maximum frequency of operation for the CD54ACT573F3A is typically limited by the propagation delay and clock skew of the device. As a general guideline, the maximum frequency of operation is around 100 MHz, but this can vary depending on the specific application and system design.
• How do I ensure that the CD54ACT573F3A is properly terminated to prevent signal reflections?
  It's recommended to use a termination resistor (e.g. 50 ohms) at the output of the device to prevent signal reflections and ensure signal integrity. The termination resistor should be placed as close to the output pin as possible.
• What is the recommended layout and routing guidelines for the CD54ACT573F3A?
  It's recommended to follow good layout and routing practices, such as keeping the signal traces short and direct, avoiding sharp corners and vias, and using a solid ground plane to reduce noise and EMI. Additionally, it's recommended to place the device close to the power supply and use decoupling capacitors to reduce noise and voltage droop.
