PCF8576DT/2,518 Frequently Asked Questions (FAQs)

• What is the maximum frequency of the I2C bus that the PCF8576 can handle?
  The PCF8576 can handle I2C bus frequencies up to 400 kHz.
• Can the PCF8576 be used as a level shifter for I2C signals?
  Yes, the PCF8576 can be used as a level shifter for I2C signals, allowing communication between devices with different voltage levels.
• How do I handle the reset pin (RST) of the PCF8576?
  The reset pin (RST) should be tied to VCC through a pull-up resistor to ensure proper operation. A low signal on the RST pin resets the device.
• What is the maximum capacitance that can be driven by the PCF8576?
  The PCF8576 can drive capacitive loads up to 400 pF.
• Can the PCF8576 be used in a multi-master I2C bus configuration?
  Yes, the PCF8576 can be used in a multi-master I2C bus configuration, but care must be taken to avoid bus contention and ensure proper arbitration.
