TLC7528IFN datasheet by Texas Instruments

TLC7528IFN Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with TLC7528IFN?
  The maximum clock frequency for TLC7528IFN 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 TLC7528IFN is properly reset after power-up?
  To ensure proper reset, apply a low pulse to the CLR pin for at least 100 ns after power-up. This will reset the internal counters and registers to their default states.
• Can I use TLC7528IFN with a 3.3V power supply?
  Yes, TLC7528IFN 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.
• How do I configure the TLC7528IFN for 8-bit or 10-bit mode?
  To configure the TLC7528IFN for 8-bit or 10-bit mode, use the MODE pin. Tie the MODE pin to VCC for 10-bit mode or to GND for 8-bit mode.
• What is the maximum output current that the TLC7528IFN can sink or source?
  The TLC7528IFN can sink or source up to 15 mA of output current per pin. However, it's recommended to limit the output current to 10 mA or less to ensure reliable operation.
