The Form Fit Function (FFF) tab will give you the options that are more likely to serve as direct pin-to-pin alternates or drop-in parts. The Functional Equivalents tab will give you options that are likely to match the same function of PCF8575CDW, but it may not fit your design. Always verify details of parts you are evaluating, as these parts are offered as suggestions for what you are looking for and are not guaranteed.
PCF8575CDW Frequently Asked Questions (FAQ)
-
The PCF8575CDW can support I2C bus frequencies up to 400 kHz, but it is recommended to operate at 100 kHz or lower for reliable operation.
-
No, the PCF8575CDW is not designed to be used as a level shifter. It is intended to be used as an I2C-bus extender or repeater, and its output voltage is the same as its supply voltage (VCC).
-
The PCF8575CDW has a built-in power-on reset (POR) circuit that resets the device when the power supply voltage (VCC) is applied. To handle POR, ensure that the I2C bus is idle during power-up, and wait for at least 1 ms after power-up before sending I2C commands.
-
Yes, the PCF8575CDW can be used to extend the I2C bus distance beyond 1 meter, but the maximum distance depends on the cable capacitance, signal frequency, and noise environment. It is recommended to use a repeater or buffer every 1-2 meters to maintain signal integrity.
-
To troubleshoot I2C bus communication issues, use a logic analyzer or oscilloscope to monitor the I2C bus signals (SCL and SDA). Check for proper signal levels, rise and fall times, and ensure that the I2C bus is not overloaded or noisy.
