PCF8574NE4 Frequently Asked Questions (FAQ)
-
The PCF8574NE4 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 PCF8574NE4 can be used as a level shifter, but it's not recommended as it's not designed for that purpose. The device is intended for I/O expansion and not for level shifting. Using it as a level shifter may lead to reliability issues.
-
The PCF8574NE4 has a built-in power-on reset (POR) circuit that resets the device when the power supply voltage (VCC) rises above 0.5V. To handle POR, ensure that the I2C bus is not active during power-up, and wait for at least 100 μs after power-up before sending I2C commands.
-
The PCF8574NE4 can source or sink up to 25 mA per I/O pin, but the total current sourced or sunk by all I/O pins should not exceed 100 mA.
-
Yes, the PCF8574NE4 is 5V tolerant, but it's recommended to use a level shifter or voltage divider to ensure that the I2C bus signals are within the recommended voltage range (VCC + 0.5V) to prevent damage to the device.
