PCA9544ARGYR Frequently Asked Questions (FAQs)

  • The PCA9544ARGYR can support I2C bus frequencies up to 400 kHz, but it's recommended to limit it to 100 kHz for reliable operation.
  • The PCA9544ARGYR is a voltage-tolerant device and can operate from 1.65V to 5.5V. To configure it for 1.8V or 3.3V operation, simply connect the VCC pin to the desired voltage supply.
  • The PCA9544ARGYR can drive capacitive loads up to 400 pF. Exceeding this limit may affect the device's performance and reliability.
  • Yes, the PCA9544ARGYR can be used as a level shifter between 3.3V and 1.8V I2C buses. However, ensure that the VCC pin is connected to the higher voltage supply (3.3V) and the I2C bus is properly terminated.
  • The PCA9544ARGYR has a typical quiescent current of 0.5 μA and a dynamic current of 1.5 mA at 100 kHz I2C bus frequency.
