The Microchip Technology MCP23S18T-E/MJ is a versatile 16-bit remote bidirectional I/O port expander designed for SPI applications. This device offers 16 general-purpose I/O pins that default to input mode and support open-drain outputs capable of sinking 25 mA per pin.
Key electrical characteristics include an operating voltage range of 1.8V to 5.5V and a high-speed SPI interface supporting up to 10 MHz. The device also features configurable interrupt output pins, which can be set as active-high, active-low, or open-drain, and a configurable interrupt source for interrupt-on-change from configured defaults or pin change.
Packaged in a 24-QFN (4x4 mm) with an exposed pad, the MCP23S18T-E/MJ is designed for surface mounting. It operates within a temperature range of -40°C to 125°C. The low standby current, 1 µA at 85°C and 6 µA at 125°C, makes it suitable for power-sensitive applications.
