PCA9534ADB Frequently Asked Questions (FAQs)

  • The PCA9534ADB can support I2C bus frequencies up to 400 kHz.
  • The PCA9534ADB can be configured for 16-bit or 8-bit port addressing by setting the A0, A1, and A2 address pins. For 16-bit addressing, A0, A1, and A2 are connected to VCC or GND to set the device address. For 8-bit addressing, A0, A1, and A2 are connected to the microcontroller's address lines.
  • Each I/O pin of the PCA9534ADB can source up to 25 mA and sink up to 25 mA.
  • The PCA9534ADB can be reset by pulling the RESET pin low for a minimum of 1 ms. This resets the device to its default state.
  • Yes, the PCA9534ADB can be used as a level translator between 1.8 V, 2.5 V, 3.3 V, and 5 V logic levels.
