Datasheet pcf8574a
WebThe PCF8574 is a silicon CMOS circuit. It provides general purpose remote I/O expansion for most microcontroller families via the two-line bidirectional bus (I2C-bus). The device … WebFeb 25, 2024 · The datasheet describes this current value to be -1mA typical while the pin is shorted to ground. In your application, this will likely be the case if the input switch is connected to ground. If this is a concern, you may consider adding a small series resistance to further limit the current during this short pull-up period.
