TLC7226IDW datasheet by Texas Instruments

TLC7226IDW Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for TLC7226IDW?
  The recommended operating voltage range for TLC7226IDW is 4.5V to 5.5V.
• How do I ensure reliable communication between the TLC7226IDW and the microcontroller?
  To ensure reliable communication, use a pull-up resistor on the SCL line, and ensure that the microcontroller's clock frequency is within the specified range of 100 kHz to 400 kHz.
• What is the maximum frequency of the internal oscillator?
  The maximum frequency of the internal oscillator is 1.2 MHz.
• Can I use the TLC7226IDW in a noisy environment?
  Yes, the TLC7226IDW has built-in noise filtering and hysteresis to improve noise immunity. However, it's still recommended to use proper PCB design and layout techniques to minimize noise coupling.
• How do I handle the power-on reset (POR) and brown-out reset (BOR) features?
  The POR and BOR features are enabled by default. To handle them, ensure that your system design can tolerate the reset pulse duration and that your software is designed to handle the reset event.
