PCA9538DB Frequently Asked Questions (FAQs)

  • The PCA9538DB can support I2C bus frequencies up to 400 kHz.
  • Yes, PCA9538DB can be used as a level shifter for I2C signals, but it's not recommended as it's not its primary function. It's designed as an 8-bit I2C-bus and SMBus I/O expander.
  • The PCA9538DB can be reset by pulling the SCL pin low for a minimum of 10 ms. This will reset the device and clear all registers.
  • Each I/O pin of PCA9538DB can source up to 25 mA and sink up to 25 mA.
  • No, PCA9538DB is an I2C-bus and SMBus I/O expander, it requires an I2C interface to communicate with the microcontroller. If your microcontroller doesn't have I2C, you'll need to use a different expander or implement a different communication protocol.
