The MIC74 is a fully programmable serial-to-parallel I/O expander compatible with the SMBus? (system management bus) protocol. It acts as a “slave” on the bus, providing eight independent I/O lines.

Features

? 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 per bus

Applications

? General purpose I/O expansion via serial bus

? Personal computer system management

? Distributed sensing and control

? Microcontroller I/O expansion

? Fan Control
