TCA9538PWR Frequently Asked Questions (FAQs)

  • The TCA9538PWR can support I2C bus frequencies up to 400 kHz.
  • The TCA9538PWR can be configured using the I2C interface to set the direction of each pin as either an input or output. The device has three registers that control the direction of the pins: the Input/Output Direction Register (IODIR), the Input/Output Polarity Inversion Register (IPOL), and the Output Value Register (OUT).
  • The TCA9538PWR can sink or source up to 25 mA per pin.
  • The TCA9538PWR can be reset to its default state by asserting the RESET pin low for a minimum of 1 ms.
  • The power-on default state of the TCA9538PWR is that all pins are configured as inputs, and the output values are undefined.
