The PCF8575TS can handle I2C bus frequencies up to 400 kHz, but it's recommended to use a frequency of 100 kHz or less to ensure reliable operation.
The PCF8575TS does not have a dedicated reset pin. However, you can reset the device by powering it down and then back up, or by sending a series of clock pulses on the SCL pin while holding the SDA pin low.
Yes, the PCF8575TS can be used as a level shifter. It can translate I2C signals from a low-voltage microcontroller to a higher voltage level, or vice versa. However, the device is not designed to handle high-speed signals, so it's not suitable for high-frequency applications.
The PCF8575TS can sink or source up to 20 mA of current per pin. However, the total current drawn from the device should not exceed 100 mA to avoid overheating.
The PCF8575TS has three address pins (A0, A1, and A2) that allow you to set the device address. You can connect these pins to VCC or GND to set the address, allowing you to connect up to 8 devices on the same I2C bus.
