PCF8574APWRE4 Frequently Asked Questions (FAQ)
-
The PCF8574APWRE4 can support I2C bus frequencies up to 400 kHz, but it is recommended to operate at 100 kHz or lower for reliable operation.
-
Yes, the PCF8574APWRE4 can be used as a level shifter for 5V to 3.3V or vice versa, but it is not recommended as it is not designed for level shifting and may not provide reliable operation.
-
The PCF8574APWRE4 can source or sink up to 25 mA of current per pin, but it is recommended to limit the current to 10 mA or less to ensure reliable operation.
-
Yes, the PCF8574APWRE4 can be used in a multi-master I2C bus configuration, but it requires careful design and consideration of bus arbitration and collision detection.
-
The PCF8574APWRE4 has a power-on reset feature that resets the device to its default state when power is applied. The device will also reset if the VCC supply voltage falls below 1.5V.
