          PCF8574AT
          Remote 8-bit I/O expander for I2C-bus
          
GENERAL DESCRIPTION
The 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 consists of an 8-bit quasi-bidirectional port and an I2C-bus interface. The PCF8574 has a low cur
