Maxim Integrated MAX7317ATE+T Product Overview

The Maxim Integrated MAX7317ATE+T is a sophisticated, low-voltage I/O expander designed to facilitate the management of complex input/output tasks within embedded systems. This device is particularly useful when additional I/O ports are needed, providing an efficient solution for expanding the capabilities of microcontrollers with a limited number of I/O pins.

Key Features

• Port Expander: Offers 10 I/O ports with selectable pull-up/pull-down resistors, enhancing the flexibility and functionality of the host controller.
• Communication: Utilizes the industry-standard 2-wire, I²C-compatible serial interface, ensuring easy integration with most microcontrollers and allowing for up to 400kbps data transfer rates.
• Operating Voltage: Compatible with a wide range of supply voltages from 2.5V to 5.5V, making it suitable for various applications and logic levels.
• Transition Detection: Features transition detection on inputs, which can signal the host controller to read the port status without the need for constant polling.
• Output Drive Capability: Each port can sink up to 50mA, providing sufficient current for driving LEDs or other low-power devices directly.
• Temperature Range: Operates over the extended temperature range of -40°C to +125°C, ensuring reliable performance in demanding environments.
• Package: Comes in a compact, 16-pin TQFN (Thin Quad Flat No-leads) package, optimizing board space.
