TCA9548AMRGER Frequently Asked Questions (FAQs)

  • The TCA9548A can handle I2C bus frequencies up to 400 kHz, which is the maximum frequency specified in the I2C bus specification.
  • The TCA9548A has three address pins (A0, A1, and A2) that can be connected to VCC or GND to set the I2C address. The address is determined by the combination of these pins, as shown in the datasheet.
  • Yes, the TCA9548A is a voltage-level translator, which means it can translate between different voltage levels on the I2C bus. However, the voltage on the VCC pin should match the voltage of the I2C bus.
  • The TCA9548A can sink or source up to 3 mA of current on the I2C bus, which is sufficient for most I2C devices.
  • The TCA9548A has a reset pin (RST) that can be used to reset the device. The reset pin should be pulled low for at least 1 ms to reset the device.
