Maxim Integrated MAX7310AUE+ I/O Expander

The Maxim Integrated MAX7310AUE+ is a versatile 8-bit I/O expander designed to provide additional digital I/O ports to a microcontroller or processor via the I²C-compatible serial interface. This powerful component is ideal for applications where I/O pin expansion is necessary, such as in embedded systems, industrial controls, and consumer electronics. Its compact TSSOP-16 package makes it suitable for space-constrained applications.

Key Features

• Port Expander: 8-bit I/O ports that can be configured as inputs or outputs, providing flexibility for a wide range of applications.
• Serial Interface: I²C-compatible serial interface that supports standard (100kHz), fast (400kHz), and high-speed (3.4MHz) operation modes, enabling easy communication with most microcontrollers.
• Output Drive Capability: Each output can sink 50mA and source up to 50mA, allowing direct driving of LEDs and other devices.
• Transition Detection: The MAX7310AUE+ can detect changes on the port inputs, which can be used to generate an interrupt signal, thereby reducing the need for continuous polling by the host processor.
• Power-Supply Voltage Range: Operates from a 2.7V to 5.5V power supply, making it suitable for both 3.3V and 5V logic levels.
• Built-in Reset: Includes a power-on reset circuit, ensuring that outputs are initialized to a known state upon power-up.

Applications

• Embedded Systems
• Industrial Controls
• Home Automation
• Server Management
• Consumer Electronics
