The MIC74 is a fully programmable serial-to-parallel I/O expander compatible with the SMBus™ (system management bus) protocol.

Provides eight bits of general purpose I/O.
Built in fan speed control logic (optional).
2-wire SMBus™/I2C™ compatible serial interface plus interrupt output.
2.7V to 3.6V operating voltage range.
5V-tolerant I/O.
Low quiescent current: 2µA (typical).
Bit-programmable I/O options: input or output push-pull or open-drain output interrupt on input changes.
Outputs can directly drive LEDs (10mA IOL).
Up to 8 devices p.
