PCA9534ARGTRG4 Frequently Asked Questions (FAQs)

  • The PCA9534 can support I2C bus frequencies up to 400 kHz, but it is recommended to operate at 100 kHz or lower for reliable operation.
  • To configure the PCA9534 to operate in 8-bit mode, set the A0 and A1 pins to VCC or GND to select the I2C address, and then write the configuration register (register 0x03) with the desired 8-bit mode setting.
  • The PCA9534 can sink or source up to 25 mA of current on each output pin, but the total current drawn from the device should not exceed 100 mA.
  • To reset the PCA9534 to its default state, pull the RESET pin low for at least 1 ms. This will reset the device to its power-on default state.
  • No, the PCA9534 is not designed to drive inductive loads such as relays or solenoids. It is recommended to use an external driver or buffer to drive such loads.
