PCF8574APWR Frequently Asked Questions (FAQ)
-
The PCF8574APWR can support I2C bus frequencies up to 400 kHz, but it's recommended to operate at 100 kHz for reliable operation.
-
The internal pull-up resistors on the I2C bus are enabled by default. To disable them, connect an external pull-up resistor to the SCL and SDA lines. The recommended value is 2.2 kΩ for 5V operation and 1.5 kΩ for 3.3V operation.
-
The PCF8574APWR can sink or source up to 25 mA on each I/O pin, but the total current should not exceed 100 mA for the entire device.
-
The PCF8574APWR can be reset by pulling the RESET pin low for at least 1 ms. This will reset the device to its default state.
-
Yes, the PCF8574APWR can be used as a level translator between 3.3V and 5V systems. The device can operate with a supply voltage range of 2.5V to 6V, making it suitable for level translation applications.
