Maxim Integrated MAX7356EUG+T I²C Port Expander

The MAX7356EUG+T from Maxim Integrated is a highly efficient, 2-wire serial interfaced I²C port expander designed to facilitate the expansion of I/O ports for microcontrollers with limited GPIOs. This device is particularly suitable for applications where additional I/Os are needed, such as in the case with embedded systems, industrial controls, and portable consumer electronics.

Providing 10 programmable I/O ports, the MAX7356EUG+T allows for a versatile configuration of input, output, or a combination thereof. Each port can be individually configured, offering a high degree of flexibility for various application requirements. This port expander operates within a voltage range of 2.3V to 3.6V, making it ideal for low-voltage operations that are common in battery-powered devices.

The MAX7356EUG+T features an interrupt output, which can be configured to alert the host microcontroller when an input state changes, thereby reducing the need for continuous polling and helping to conserve system power. This interrupt feature is invaluable in power-sensitive applications where efficient resource use is paramount.

With its built-in ESD protection, the MAX7356EUG+T ensures robustness and reliability, safeguarding the device against electrostatic discharges and other transient voltage spikes that are common in industrial environments. The device comes in a compact TSSOP-24 package, offering a space-saving solution for PCB designs where board real estate is at a premium.

The MAX7356EUG+T supports hot insertion, which means it can be added to a live system without needing to power down or restart, increasing the system's uptime and serviceability. Additionally, the device's I²C-bus interface supports the standard (100kHz) and fast (400kHz) I²C modes, providing flexibility in communication speed based on the system requirements.

In summary, the Maxim Integrated MAX7356EUG+T is a versatile, low-voltage I²C port expander that is perfect for expanding I/O capabilities in space-constrained and power-sensitive applications. Its programmable interface, integrated ESD protection, and interrupt feature make it a reliable and efficient choice for designers looking to enhance their system's I/O functionality.
