MAX7328AAP+T

I/o Expanders Overview

The MAX7328AAP+T is an I/O expander featuring eight general-purpose input/output ports controlled via a serial interface. It operates within a supply voltage range of 2.5 V to 5.5 V and supports clock frequencies up to 100 kHz. The device is designed for surface-mount installation in SSOP-20 packages, functioning reliably across an extended temperature range from -40°C to +125°C. This component serves as a software-compatible expansion solution for systems requiring additional digital control lines without consuming excessive microcontroller resources.

I/o Expanders Feature Summary

• Provides eight configurable general-purpose I/O ports for system expansion
• Supports standard serial communication protocols for efficient data transfer
• Ensures reliable operation across wide industrial temperature extremes
• Offers software compatibility with related port expander devices

I/o Expanders Applications

• Storage Area Network (SAN) and Network Attached Storage (NAS) systems
• Industrial and medical equipment requiring expanded I/O capabilities

I/o Expanders Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm package type and temperature grade accuracy. Ensure that the selected variant matches the required thermal performance and physical footprint specifications for the target design. Cross-reference part numbers with authorized distributors to confirm availability status and authenticity before procurement.

I/o Expanders Selection Notes

Select this component when eight dedicated I/O lines are required alongside broad industrial temperature tolerance. Consider the SSOP-20 package constraints regarding board space and pin density. Evaluate the need for interrupt functions, as this specific variant lacks dedicated interrupt outputs compared to other family members. Confirm power supply stability within the specified voltage limits during operation.

I/o Expanders Part Context

This device belongs to the MAX7328 series of I/O expanders manufactured by Analog Devices under the Maxim Integrated brand. It is functionally compatible with other eight-port devices in the family, allowing mixed configurations. The series targets applications needing flexible I/O management in computing and communication infrastructure environments.

I/o Expanders Replacement Considerations

The MAX7328AWE+ is a verified alternative offering identical functionality in a SOIC-Wide-16 package. Verify pinout compatibility and thermal characteristics when substituting between SSOP and SOIC footprints.
