MAX3227EEAE/V+T

Overview

The MAX3227EEAE/V+T is a single-driver, single-receiver full-duplex RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a +3.0V to +5.5V supply and achieves a guaranteed data rate of 1Mbps. The device incorporates AutoShutdown Plus technology, reducing supply current to 1μA when idle. It features ±15kV ESD protection on all I/O pins and includes an INVALID output for signal detection. Packaged in a 16-pin SSOP with exposed pad, it supports automotive-grade reliability under AEC-Q100 standards.

Feature Summary

• AutoShutdown Plus functionality automatically reduces power consumption by shutting down charge pumps during periods of inactivity.
• Integrated dual charge pump generates internal ±5.5V supplies from a single low-voltage source using minimal external capacitors.
• Robust electrostatic discharge protection ensures signal integrity across transmitter outputs and receiver inputs.
• INVALID logic output provides real-time status indication regarding the presence of valid RS-232 voltage levels.

Applications

• Automotive infotainment and telematics systems requiring AEC-Q100 compliance
• Battery-powered portable equipment utilizing low-power communication interfaces
• Industrial handheld devices operating in environments with high electromagnetic interference

Procurement Notes

Verify that the specific suffix /V+T corresponds to the required automotive qualification (AEC-Q100) and tape-and-reel packaging format. Confirm the temperature range aligns with system requirements, as the EE variant typically covers -40°C to +85°C. Ensure ordering documentation matches the exact manufacturer part number to avoid discrepancies in RoHS compliance or package dimensions.

Selection Notes

Select this component when a single-channel RS-232 interface with high-speed 1Mbps capability is necessary. It is suitable for designs prioritizing ultra-low standby power through automatic shutdown mechanisms. Consider this part over standard variants if automotive reliability certification is mandatory. Verify that the 16-SSOP footprint fits the available PCB space constraints.

Part Context

This device belongs to the MAX3227E family of true RS-232 transceivers designed for 3V operation. It shares architectural similarities with the MAX3224E and MAX3225E but offers distinct driver/receiver counts and speed ratings. The MAX3227E specifically targets applications needing one transmitter and one receiver at maximum baud rates within the series.
