SN74BCT574DW datasheet by Texas Instruments

SN74BCT574DW Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74BCT574DW?
  The maximum operating frequency of the SN74BCT574DW 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 SN74BCT574DW?
  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 SN74BCT574DW?
  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 reflections and ensure signal integrity.
• Can I use the SN74BCT574DW in a 3.3V system?
  Yes, the SN74BCT574DW is compatible with 3.3V systems, but the input voltage threshold may be affected, and the output voltage may not reach the full 3.3V level.
• How do I handle the thermal management of the SN74BCT574DW?
  The SN74BCT574DW has a maximum junction temperature of 150°C, and it is recommended to use a heat sink or thermal pad to keep the junction temperature below 120°C for reliable operation.
