MCP23017 16-BIT I2C I/O EXPANDER

$10.00

The MCP23017 device family provides 16-bit, general purpose parallel I/O expansion for I2C bus applications. The two devices differ only in the serial interface. 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 MCP23017 device family provides 16-bit, general purpose parallel I/O expansion for I2C bus applications. The two devices differ only in the serial interface. 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.

MCP23017 FEATURES

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 modes
