MAX3221EEAE/GG8

Overview

The MAX3221EEAE/GG8 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 pins and utilizes a dual charge pump requiring four 0.1µF capacitors for operation.

Feature Summary

AutoShutdown technology enables ultra-low power consumption by automatically disabling the charge pump and drivers when the RS-232 cable is disconnected or peripheral transmitters are off.
Integrated dual charge pumps generate internal +5.5V and -5.5V supplies from a single low-voltage source using external capacitors.
Comprehensive electrostatic discharge protection rated at ±15kV via Human Body Model and IEC 1000-4-2 standards ensures robustness during handling and assembly.

Applications

Notebook, subnotebook, and palmtop computers
Battery-powered handheld equipment and peripherals
Cellular phones and portable devices

Procurement Notes

Verify the specific suffix GG8 against official manufacturer documentation to confirm package type and temperature range. Confirm availability status as this component family may have discontinued variants. Ensure compatibility with existing BIOS or operating system configurations if utilizing the AutoShutdown feature.

Selection Notes

Select this component for space-constrained applications requiring minimal driver and receiver counts. Verify that the required data rate does not exceed 250kbps. Ensure the design accommodates the necessary external 0.1µF capacitors for the charge pump circuitry within the specified voltage range.

Part Context

This part belongs to the MAX3221E/MAX3223E/MAX3243E family of RS-232 transceivers. While the MAX3221E provides one driver and one receiver, other family members offer increased channel counts. All share the same core architecture, including the AutoShutdown feature and ESD protection capabilities.
