TLC7705IDR datasheet by Texas Instruments

TLC7705IDR Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for TLC7705IDR?
  The recommended operating voltage range for TLC7705IDR is 2.7V to 5.5V.
• How do I ensure the TLC7705IDR is properly powered on?
  To ensure proper power-on, the VCC pin should be ramped up slowly (typically within 1ms) to the desired operating voltage, and the VCC pin should be decoupled with a 0.1uF capacitor to GND.
• What is the maximum current that can be sourced or sunk by the TLC7705IDR?
  The TLC7705IDR can source or sink up to 25mA of current per output pin.
• How do I handle the thermal shutdown feature of the TLC7705IDR?
  The TLC7705IDR has a built-in thermal shutdown feature that activates when the junction temperature exceeds 150°C. To handle this, ensure proper heat sinking, reduce power consumption, or implement a thermal monitoring system.
• What is the purpose of the EN (enable) pin on the TLC7705IDR?
  The EN pin is an active-low input that enables or disables the TLC7705IDR. When EN is low, the device is enabled, and when EN is high, the device is disabled and all outputs are high-impedance.
