MAX7314ATG+TG05

Overview

The MAX7314ATG+TG05 is an 18-port GPIO peripheral with I2C-compatible serial interface. It provides 16 configurable I/O ports and one output-only port (INT/O16). Each I/O port supports open-drain current-sinking outputs rated at 50mA and 5.5V, or logic inputs with transition detection. The device operates on a supply voltage of 2V to 3.6V. It features an overall 8-bit PWM LED intensity control with global and individual 16-step controls. The serial interface supports clock frequencies up to 400kHz. Operating current is typically 1.2µA in standby mode.

Feature Summary

Supports hot insertion with high-impedance state during power-down
Includes built-in 8-bit PWM current control for LED intensity adjustment
Features transition detection with interrupt output capability
Provides overvoltage protection on inputs up to 5.5V

Applications

LCD Backlights
LED Status Indication
Relay Drivers
Keypad Backlights
RGB LED Drivers

Procurement Notes

Verify the component matches the exact part number MAX7314ATG+TG05. Confirm the manufacturer is Analog Devices Inc./Maxim Integrated. Check the datasheet revision and date code to ensure compatibility with design requirements. Ensure the package type corresponds to the 24-pin Thin QFN specification.

Selection Notes

Select this component when an I2C GPIO expander with integrated LED driving capabilities is required. Consider the 50mA sink current rating and 5.5V tolerance for interfacing with various loads. Evaluate the 2V to 3.6V operating voltage range against the system power supply. Verify that the 400kHz I2C speed meets the communication requirements.

Part Context

The MAX7314 is part of the Maxim Integrated I/O expander family. It is designed for applications requiring multiple general-purpose I/O lines and LED control through a single serial interface. The ATG suffix indicates the -40°C to +125°C temperature range and the 24-pin Thin QFN package.

Replacement Considerations

Check for direct pin-to-pin replacements within the same product family. Verify electrical characteristics such as supply voltage, current ratings, and interface compatibility before substitution.
