PCA6416APW,118 datasheet by NXP Semiconductors

PCA6416APW,118 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for PCA6416APW,118?
  The recommended operating voltage range for PCA6416APW,118 is 2.3V to 5.5V.
• How do I ensure reliable communication with the PCA6416APW,118?
  To ensure reliable communication, make sure to use a pull-up resistor on the SCL line, and use a clock frequency within the recommended range of 100 kHz to 400 kHz.
• What is the maximum current rating for the PCA6416APW,118?
  The maximum current rating for the PCA6416APW,118 is 10mA per pin, with a total device current limit of 50mA.
• How do I handle the power-on reset (POR) and brown-out detection (BOD) features of the PCA6416APW,118?
  The PCA6416APW,118 has a built-in POR and BOD circuitry. The POR ensures that the device resets properly during power-up, and the BOD detects voltage drops and resets the device if the voltage falls below a certain threshold.
• What is the purpose of the reset pin (RST) on the PCA6416APW,118?
  The reset pin (RST) is an active-low input that resets the device when pulled low. It can be used to reset the device in case of a fault or to initialize the device during power-up.
