간략설명	Microchip 16-Channel I/O Expander I2C 28-Pin SSOP, MCP23017T-E/SS

■ 제품사양

Number of I/O Channels = 16 Interface = I2C Number of Pins = 28
패키지 = SSOP Clock Frequency = 10MHz
장착형태 = Surface Mount Maximum Supply Voltage = 5.5 V Minimum Supply Voltage = 1.8 V The MCP23X17 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 (IODIRA/B). 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. The 16-bit I/O port functionally consists of two 8-bit ports (PORTA and PORTB).16-bit input/output port expander with interrupt output Cascadable for up to 8 devices on one bus 25mA sink/source capability per I/O Supports 100kHz, 400kHz and 1.7MHz I2C??Compatible compatible modes
