MAX1608EEE

Overview

The MAX1608EEE is an octal SMBus-to-parallel I/O expander manufactured by Analog Devices / Maxim Integrated. It operates within a supply voltage range of 2.7 V to 5.5 V and supports standard mode clock frequencies up to 100 kHz. The device features eight general-purpose I/O pins with open-drain outputs and includes an interrupt output capability. It functions across a temperature range of -40°C to +85°C, consuming only 7 µA of operating current. Packaged in a 16-pin QSOP format, it serves as a serial-to-parallel interface solution for embedded systems requiring expanded digital input and output capabilities.

Feature Summary

• Provides expansion from SMBus or I2C serial interfaces to eight parallel digital I/O lines
• Includes dedicated interrupt output pin to signal state changes on the I/O ports
• Supports low-power operation suitable for battery-powered applications

Applications

• Embedded controller peripheral expansion
• Industrial control system I/O interfacing
• Consumer electronics port expansion

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific suffix designations against official datasheets prior to integration. Ensure storage conditions meet moisture sensitivity level requirements to maintain package integrity during assembly processes.

Selection Notes

Select this component when an application requires converting a two-wire serial bus into multiple parallel GPIO lines. Verify that the target system voltage aligns with the 2.7 V to 5.5 V operational range. Consider the QSOP-16 footprint constraints and thermal dissipation characteristics relative to the board layout and ambient operating environment.

Part Context

This part belongs to the MAX1609 series of SMBus-compatible I/O expanders. It shares functional similarities with other devices in the family but offers specific pin configurations and electrical characteristics tailored for octal expansion needs. The component represents a specialized interface solution within the broader portfolio of Maxim Integrated analog and mixed-signal products.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains compatibility with SMBus protocols and matches the required voltage and current specifications.
