MAX7328AAP+

Overview

The MAX7328AAP+ is an I/O expander manufactured by Analog Devices Inc./Maxim Integrated, belonging to the MAX7328 series. It features eight general-purpose I/O ports and communicates via an I2C serial interface. The device operates within a supply voltage range of 2.5 V to 5.5 V and supports a maximum clock frequency of 100 kHz. It is housed in an SSOP-20 package designed for surface mount installation. The component functions without interrupt outputs or ESD protection mechanisms. It is rated for operation across a temperature range from -40°C to +125°C.

Feature Summary

Provides eight configurable general-purpose input/output ports for system expansion
Interfaces with host processors using standard I2C serial communication protocols
Operates reliably across extended industrial temperature ranges

Applications

General computing systems requiring additional control lines
Communication equipment needing port expansion
Consumer electronics devices with limited pin counts
Industrial control interfaces
Medical instrumentation peripheral connections

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status prior to integration. Check current availability as supply may be restricted. Ensure packaging integrity matches specification requirements. Validate datasheet revisions against design specifications.

Selection Notes

Compare electrical characteristics with alternative I/O expanders. Verify package compatibility with existing PCB footprints. Assess thermal performance within the intended operating environment. Confirm interface protocol alignment with the main processor. Evaluate long-term availability for production runs.

Part Context

This component belongs to the MAX7328 family of I/O expanders. It serves as an eight-port solution compatible with PCF8574 standards. The series includes variants with different packages and temperature ratings. These devices are designed to extend system connectivity efficiently.

Replacement Considerations

The MAX7328AWE+ offers identical functionality in a SOIC-Wide-16 package. Verify pinout compatibility before substitution. Ensure voltage and temperature specifications match application requirements.
