- **Package:** 16-pin QSOP (MAX7310AEE)
### **Descriptions:**
The MAX7310AEE is a low-voltage, 16-bit I/O expander with an I²C-compatible serial interface. It provides general-purpose remote I/O expansion for microcontrollers via the two-wire I²C interface. Each of the 16 I/O pins can be independently configured as an input or output. The device includes an interrupt output that signals changes in input states, reducing the need for continuous polling.
### **Features:**
- **Wide Voltage Operation:** Supports 1.65V to 5.5V for compatibility with various logic levels.
- **Low Standby Current:** Consumes only 1µA in shutdown mode.
- **Configurable I/O Pins:** Each of the 16 I/Os can be set as input or output.
- **Interrupt Output:** Alerts the host of input changes without polling.
- **High Drive Capability:** 20mA sink/source per I/O pin.
- **I²C Fast-Mode (400kHz) Interface:** Allows high-speed communication.
- **Industrial Temperature Range:** Operates from -40°C to +125°C.
