Microchip (MCP23008-E/SS) I/O Expander, 8bit, 1.7 MHz

Product Overview
The MCP23008-E/SS is a 8-bit general purpose, parallel I/O Expansion for I²C bus applications. It consists of multiple 8-bit configuration registers for input, output and polarity selection. The system master can enable the I/Os as either inputs or outputs by writing the I/O configuration bits. The data for each input or output is kept in the corresponding input or output register. The polarity of the input port register can be inverted with the polarity inversion register. All registers can be read by the system master.

3 Address inputs for up to 8 devices on one bus
25mA Sink/source capability per I/O
Supports 100kHz, 400kHz and 1.7MHz I²C™ compatible modes
Internal power-on-reset (POR)
Polarity inversion register to configure polarity of input port data
External reset input
1µA (maximum) Low standby current
