SN74ACT573NSR datasheet by Texas Instruments

SN74ACT573NSR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74ACT573NSR?
  The maximum operating frequency of the SN74ACT573NSR is 100 MHz, but it can vary depending on the system design and capacitive load.
• How do I handle the power-up and power-down sequencing of the SN74ACT573NSR?
  It is recommended to power up the VCC pin before the input signals and power down the VCC pin after the input signals to prevent unwanted output states.
• What is the recommended termination scheme for the SN74ACT573NSR?
  The recommended termination scheme is to use a 33-ohm series resistor and a 47-pF capacitor to ground on each output pin to minimize ringing and ensure signal integrity.
• Can I use the SN74ACT573NSR in a 3.3V system?
  Yes, the SN74ACT573NSR is compatible with 3.3V systems, but the input voltage must not exceed 3.6V to prevent damage to the device.
• How do I handle the thermal management of the SN74ACT573NSR?
  The device has a thermal pad on the bottom that must be connected to a thermal plane on the PCB to dissipate heat. A thermal interface material (TIM) can be used to improve heat transfer.
