TLC7528CFN Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with TLC7528CFN?
  The maximum clock frequency for TLC7528CFN is 40 MHz. However, it's recommended to use a clock frequency of 20 MHz or less for reliable operation.
• How do I ensure that the TLC7528CFN outputs are not corrupted during power-up or power-down?
  To prevent output corruption during power-up or power-down, it's recommended to use an external reset circuit to hold the TLC7528CFN in a reset state until the power supply has stabilized. Additionally, ensure that the clock input is stable and valid before releasing the reset.
• Can I use TLC7528CFN with a 3.3V power supply?
  Yes, TLC7528CFN can operate with a 3.3V power supply. However, the output voltage swing will be reduced, and the device may not meet the specified timing parameters. For optimal performance, it's recommended to use a 5V power supply.
• How do I handle the thermal dissipation of TLC7528CFN?
  TLC7528CFN has a maximum junction temperature of 150°C. To ensure reliable operation, it's recommended to provide adequate heat sinking and thermal dissipation measures, such as using a heat sink or a thermally conductive PCB material.
• Can I use TLC7528CFN in a radiation-hardened application?
  No, TLC7528CFN is not designed for radiation-hardened applications. It's recommended to use radiation-hardened devices specifically designed for such applications.
