TLC552CN datasheet by Texas Instruments

TLC552CN Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of TLC552CN?
  The TLC552CN can operate up to 100 kHz, but it's recommended to operate at 50 kHz or lower for optimal performance and to minimize power consumption.
• How do I ensure the TLC552CN is properly powered?
  The TLC552CN requires a single 5V power supply (VCC) and a ground connection (GND). Ensure that the power supply is clean and stable, and that the device is properly decoupled with a 0.1uF ceramic capacitor between VCC and GND.
• What is the purpose of the CLR pin?
  The CLR (Clear) pin is an active-low input that resets the TLC552CN's internal counters and sets the output to zero. It's typically used to synchronize the device with other components or to reset the device during power-up.
• How do I interface the TLC552CN with a microcontroller?
  The TLC552CN can be interfaced with a microcontroller using a 3-wire serial interface (CLK, DIN, and DOUT). The microcontroller can send commands and data to the TLC552CN using the DIN pin, and receive data from the TLC552CN using the DOUT pin.
• What is the maximum output current of the TLC552CN?
  The TLC552CN can sink up to 25mA of current per output pin, making it suitable for driving LEDs, relays, and other low-power devices.
