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 Applications Industrial Product Information Chip Configuration: 8bit Bus Frequency: 1.7MHz IC Interface Type: I2C Supply Voltage Min: 1.8V Supply Voltage Max: 5.5V Interface Case Style: SSOP No. of Pins: 20Pins No. of I/O's: 8I/O's Product Range: - Automotive Qualification Standard: - MSL: -
