MAX3221EEAE+G071

Overview

The MAX3221EEAE+G071 is a single-driver, single-receiver RS-232 transceiver from Analog Devices/Maxim Integrated. It operates on a +3.0V to +5.5V supply and supports data rates up to 250kbps. The device features an AutoShutdown function that reduces supply current to 1µA when no valid signal is detected. It includes ±15kV ESD protection on all I/O pins and utilizes a dual charge pump requiring four 0.1µF capacitors for operation.

Feature Summary

• AutoShutdown technology enables ultra-low power consumption by entering shutdown mode when the cable is disconnected or peripherals are off.
• Integrated dual charge pumps generate true RS-232 voltage levels directly from a single low-voltage supply.
• Enhanced electrostatic discharge protection ensures robustness against high-voltage static events without latchup.

Applications

• Notebook, subnotebook, and palmtop computers
• Cellular phones and handheld equipment
• Battery-powered peripherals and printers

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status as indicated in official documentation. Check for lead-free packaging specifications. Ensure the ordering suffix matches the required temperature range and package type. Validate part availability status prior to finalizing procurement plans.

Selection Notes

Select this specific variant for applications requiring a single driver and receiver within a space-constrained 16-pin SSOP package. Verify that the -40°C to +85°C industrial temperature rating aligns with system requirements. Ensure the design accommodates the necessary external capacitors for the internal charge pump circuitry.

Part Context

This component belongs to the MAX3221E/MAX3223E/MAX3243E family of RS-232 transceivers. The EE suffix denotes the extended industrial temperature range (-40°C to +85°C). The AE suffix indicates the 16-pin SSOP package configuration. The G071 suffix represents a specific manufacturing lot or revision code.

Replacement Considerations

Direct functional substitutes include other parts from the MAX3221E series with compatible packages and temperature ratings. Verify pinout compatibility before substitution. Consider the MAX3222E or MAX3232E if additional drivers are required.
