TLC59281DBQ datasheet by Texas Instruments

TLC59281DBQ Frequently Asked Questions (FAQs)

• What is the maximum current that can be sourced or sunk by each output?
  The TLC59281DBQ can source up to 25mA and sink up to 50mA per output.
• How do I ensure that the device is properly powered up and initialized?
  The device requires a power-on reset (POR) circuit to ensure proper initialization. A 0.1uF capacitor between VCC and GND, and a 10kΩ resistor between VCC and RESET can be used to create a POR circuit.
• What is the recommended clock frequency for the TLC59281DBQ?
  The recommended clock frequency is between 10kHz and 25MHz. However, the device can operate up to 40MHz with reduced performance.
• How do I handle the thermal shutdown feature?
  The TLC59281DBQ has a built-in thermal shutdown feature that activates when the junction temperature exceeds 150°C. To handle this, ensure proper heat sinking, reduce the output current, or implement a thermal monitoring circuit.
• What is the purpose of the OE (Output Enable) pin?
  The OE pin is used to enable or disable the output drivers. When OE is low, the outputs are enabled, and when OE is high, the outputs are high-impedance.
