I²C Port Expander with Eight Push-Pull Outputs The MAX7320AEE+ is a serial-interfaced peripheral manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:
### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)
- **Part Number:** MAX7320AEE+
- **Package:** 16-QSOP
- **Interface:** I²C-compatible 2-wire serial interface
- **Operating Voltage:** 2.5V to 5.5V
- **Number of I/O Ports:** 8 (individually configurable as inputs or outputs)
- **Output Current (per pin):** 20mA (sink/source)
- **Operating Temperature Range:** -40°C to +85°C
- **Interrupt Output:** Configurable for input state change detection
- **Internal Pull-Up Resistors:** 100kΩ (default)
### **Description:**
The MAX7320AEE+ is an I²C-controlled 8-bit GPIO expander that provides additional input/output ports for microcontrollers. It features an interrupt output that alerts the host when an input state changes, reducing the need for continuous polling. The device is designed for low-voltage operation and is commonly used in industrial, consumer, and embedded systems for expanding I/O capabilities.
### **Features:**
- **8 Programmable I/O Pins:** Each pin can be independently configured as an input or output.
- **I²C-Compatible Interface:** Supports standard (100kHz) and fast (400kHz) modes.
- **Interrupt Output:** Notifies the host of input changes for efficient event handling.
- **Internal Pull-Up Resistors:** Default 100kΩ pull-ups (can be disabled via software).
- **Low Standby Current:** Suitable for power-sensitive applications.
- **Wide Voltage Range:** Operates from 2.5V to 5.5V, compatible with 3.3V and 5V systems.
- **Small Footprint:** 16-QSOP package for space-constrained designs.
