General Description
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.
Each I/O bit can be individually programmed as an input or output.
Key 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 p.
