PCA9654E, PCA9654EA 8-bit I/O Expander for I2C Bus and SMBus with Interrupt The PCA9654E/PCA9654EA provides 8 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C bus/SMBus applications.

The PCA9654E/PCA9654EA consists of 8 bit Configuration (Input or Output selection), Input, Output and Polarity Inversion (active HIGH or active LOW operation) registers.

The system master may set the I/Os as either inputs or outputs by writing to the I/O configuration bits.
