Description: 16-Bit I/O Expander

Features

* 16-bit remote bidirectional I/O port: - I/O pins default to input
* Open-drain outputs: - 5.5V tolerant - 25 mA sink capable (per pin) - 400 mA total
* High-speed I2C™ interface: (MCP23018) - 100 kHz - 400 kHz - 3.4 MHz
* High-speed SPI interface: (MCP23S18) - 10 MH

Applications

* The two devices differ only in the serial interface.
* MCP23018 - I2C interface
* MCP23S18 - SPI interface The MCP23X18 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 w
