PCA8574TS Frequently Asked Questions (FAQs)

  • The PCA8574TS can support I2C bus frequencies up to 400 kHz, but it's recommended to limit it to 100 kHz for reliable operation.
  • Yes, PCA8574TS can be used as a level shifter for 5V to 3.3V or vice versa, but it's essential to ensure that the input voltage on the device does not exceed the recommended maximum rating.
  • It's recommended to power up the PCA8574TS after the I2C bus is stable and powered up. During power-down, ensure that the I2C bus is idle and the PCA8574TS is powered down last.
  • The PCA8574TS can drive capacitive loads up to 400 pF, but it's recommended to limit it to 100 pF for reliable operation.
  • Yes, PCA8574TS can be used in hot-swappable applications, but it's essential to ensure that the device is properly powered down before removal and powered up after insertion.
