MAX3227ECUE+

Overview

The MAX3227ECUE+ is a single-channel, full-duplex RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +3.0V to +5.5V supply and achieves a guaranteed data rate of 1Mbps using MegaBaud technology. The device incorporates AutoShutdown Plus, reducing supply current to 1μA when idle. It features ±15kV ESD protection (Air-Gap, Contact, Human Body Model) and includes a READY output indicating charge pump regulation. The component is housed in a 16-pin TSSOP package and supports an operating temperature range of 0°C to +70°C.

Feature Summary

• AutoShutdown Plus functionality automatically reduces power consumption by shutting down internal charge pumps during periods of inactivity.
• Integrated dual charge pump generates required positive and negative voltage rails from a single low-voltage supply.
• Enhanced electrostatic discharge protection ensures robustness against high-voltage static events on all I/O lines.

Applications

• Notebook, Subnotebook, and Palmtop Computers
• Cellular Phones
• Battery-Powered Equipment
• Hand-Held Equipment
• Automotive

Procurement Notes

Verify the specific suffix 'ECUE+' against official manufacturer documentation to confirm the exact pinout, thermal characteristics, and environmental compliance status. Ensure that the ordering information matches the intended application requirements for temperature range and package dimensions before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring a single RS-232 channel with high-speed 1Mbps data rates. It is suitable for battery-powered systems due to its ultra-low shutdown current. Verify that the system design accommodates the external 0.1μF capacitors required for the internal charge pump operation within the specified voltage range.

Part Context

This part belongs to the MAX3224E–MAX3227E family of RS-232 transceivers. While sharing core features like AutoShutdown Plus and ESD protection, variants differ in channel count and guaranteed data rates. The MAX3227E specifically provides one driver and one receiver with 1Mbps capability, distinguishing it from lower-speed or multi-channel counterparts in the series.
