TLC7226CDW datasheet by Texas Instruments

TLC7226CDW Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for TLC7226CDW?
  The recommended operating voltage range for TLC7226CDW is 4.5V to 5.5V.
• How do I ensure the TLC7226CDW is properly powered up and initialized?
  To ensure proper power-up and initialization, apply a stable voltage supply, ensure all input pins are at a valid logic level, and wait for the internal power-on reset (POR) to complete before applying clock signals.
• What is the maximum clock frequency supported by TLC7226CDW?
  The TLC7226CDW supports clock frequencies up to 40 MHz.
• How do I handle the output enable (OE) pin to ensure proper data output?
  The OE pin should be tied low to enable the output drivers. When OE is high, the output drivers are in a high-impedance state.
• What is the purpose of the internal pull-up resistors on the input pins?
  The internal pull-up resistors on the input pins are used to ensure that the inputs are at a valid logic level when not driven by an external signal.
