PCA9536DP datasheet by Philips Semiconductors

PCA9536DP Frequently Asked Questions (FAQs)

• What is the maximum frequency of the I2C bus that the PCA9536DP can support?
  The PCA9536DP can support I2C bus frequencies up to 400 kHz, but it is recommended to operate at 100 kHz or lower for reliable operation.
• How do I reset the PCA9536DP?
  The PCA9536DP can be reset by pulling the RESET pin low for at least 1 ms. This will reset the device to its default state.
• What is the maximum current that the PCA9536DP can sink or source on each output pin?
  The PCA9536DP can sink or source up to 25 mA on each output pin, but it is recommended to limit the current to 10 mA or less to ensure reliable operation.
• Can I use the PCA9536DP as a level translator between 3.3V and 5V systems?
  Yes, the PCA9536DP can be used as a level translator between 3.3V and 5V systems, but it is recommended to use external resistors to limit the current and voltage on the output pins.
• How do I configure the PCA9536DP to operate in a specific mode (e.g. input, output, etc.)?
  The PCA9536DP can be configured using the I2C bus by writing to the configuration registers. The specific configuration depends on the desired mode of operation, and can be found in the datasheet.
