Integrated circuits

With this multiplexer circuit we will be able to get 8 more digital outputs for arduino losing only 3 of them. 

- The PCF8574P is an 8-bit remote I / O expander for the I2C bus with 16-pin DIP packet interrupt. - Provides general-purpose remote I / O expansion via a two-wire, two-way I2C bus (Serial Clock (SCL), Serial Data (SDA)).
- Devices consist of eight quasi-directional ports , 100KHz I2C bus interface, three hardware address inputs and interrupt output operating between 2.5V and 6V.
- Quasi-bidirectional port can be independently assigned as one input to monitor interrupt status or keyboards or as an output to activate indicating devices like LEDs. - System Master can read from the input port or write to the output port through a single register.
