The Microchip Technology MCP23S18-E/SP is a versatile 16-bit remote bidirectional I/O port expander designed for SPI applications. It provides 16 general-purpose I/O pins that default to input and feature open-drain outputs capable of sinking 25 mA per pin.
This device supports a high-speed SPI interface with a clock frequency of up to 10 MHz. It operates within a voltage range of 1.8V to 5.5V and has a configurable interrupt output. The operating temperature range is from -40°C to +125°C, making it suitable for various environmental conditions. Standby current is as low as 1 µA.
The MCP23S18-E/SP is available in a 28-pin PDIP package, designed for through-hole mounting. Its open-drain output characteristic and configurable interrupt source provide flexibility in system design.
Key electrical specifications include a 10 MHz SPI interface, 1.8V to 5.5V operating voltage, and 25 mA sink capability per pin. The device also offers configurable interrupt pins and a polarity inversion register for input port data.
