TLC7524IN datasheet by Texas Instruments

TLC7524IN Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with TLC7524IN?
  The maximum clock frequency for TLC7524IN 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 TLC7524IN is properly reset after power-up?
  To ensure proper reset, connect the RESET pin to a 10 kΩ pull-up resistor to VCC, and apply a reset pulse of at least 100 ns width after power-up. This will ensure that the device is properly initialized.
• What is the recommended output current for the TLC7524IN?
  The recommended output current for TLC7524IN is up to 25 mA per channel. Exceeding this current may cause overheating and reduce the device's lifespan.
• Can I use TLC7524IN with a 3.3V supply voltage?
  Yes, TLC7524IN can operate with a supply voltage as low as 3.3V. However, the output voltage swing may be reduced, and the device's performance may be affected.
• How do I handle the thermal shutdown feature of TLC7524IN?
  The TLC7524IN has a built-in thermal shutdown feature that activates when the junction temperature exceeds 150°C. To handle this, ensure good thermal design and heat dissipation, and consider adding thermal monitoring and shutdown circuitry to prevent overheating.
