PCA9674/74A
Remote 8-bit I/O expander for Fm+ I2C-bus with interrupt
The last bit of the first byte defines the operation to be performed. When set to logic 1 a
read is selected, while a logic 0 selects a write operation.
When AD2, AD1 and AD0 are held to VDD or VSS, the same address as the PCF8574 or
PCF8574A is applied.
