간략설명	Microchip 8-Channel I/O Expander I2C 18-Pin SOIC, MCP23008T-E/SO

■ 제품사양

Number of I/O Channels = 8 Interface = I2C Number of Pins = 18
패키지 = SOIC Clock Frequency = 10MHz
장착형태 = Surface Mount Maximum Supply Voltage = 5.5 V Minimum Supply Voltage = 1.8 V The MCP23X08 device provides 8-bit, general purpose, parallel I/O expansion for I2C bus or SPI applications. The two devices differ in the number of hardware address pins and the serial interface: MCP23008 ??I2C interface, three address pinsMCP23S08 ??SPI interface, two address pins The MCP23X08 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.Additional Features: 8-bit port expander with interrupt output 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)
