TLC7528EDW Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with TLC7528EDW?
  The maximum clock frequency for TLC7528EDW 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 TLC7528EDW is properly initialized after power-up?
  To ensure proper initialization, the TLC7528EDW requires a reset pulse on the CLR pin after power-up. The reset pulse should be at least 100 ns wide and have a voltage level below 0.8 V.
• What is the recommended output current for the TLC7528EDW?
  The recommended output current for the TLC7528EDW is 5 mA per channel. Exceeding this current may cause overheating and reduce the device's reliability.
• Can I use the TLC7528EDW with a 3.3 V power supply?
  Yes, the TLC7528EDW can operate with a 3.3 V power supply. However, the output voltage swing will be reduced, and the device's performance may be affected.
• How do I handle the thermal dissipation of the TLC7528EDW?
  To handle thermal dissipation, ensure that the TLC7528EDW is mounted on a PCB with a thermal pad connected to a ground plane. Additionally, use thermal vias to dissipate heat to the other side of the PCB.
