MAX3227EEUE+T

Overview

The MAX3227EEUE+T is a single-driver, single-receiver RS-232 transceiver from the MAX3227E family. It operates on a +3.0V to +5.5V supply and supports data rates up to 1Mbps. The device features AutoShutdown Plus technology, reducing supply current to 1μA when inputs are idle for over 30 seconds. It includes ±15kV ESD protection on all I/O pins and utilizes a dual charge pump with four 0.1μF capacitors. The component is housed in a 16-pin TSSOP package and functions within an operating temperature range of -40°C to +85°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 RS-232 voltage levels using only four small external capacitors.
• Enhanced electrostatic discharge protection ensures robustness against high-voltage static events on transmitter and receiver lines.

Applications

• Notebook, subnotebook, and palmtop computers
• Cellular phones and battery-powered equipment
• Automotive systems

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging rather than tube packaging. Confirm that the 'EE' designation corresponds to the extended industrial temperature range of -40°C to +85°C. Ensure the '+T' suffix aligns with lead-free and RoHS compliance requirements specified in the ordering information.

Selection Notes

Select this part for applications requiring full-duplex communication at speeds up to 1Mbps. It is suitable for space-constrained designs due to the compact TSSOP-16 package. Consider the low standby current benefit if the system requires minimal power drain during long periods of idle RS-232 bus activity.

Part Context

This component belongs to the MAX3224E through MAX3245E series of 3V-powered RS-232 interfaces. Unlike the MAX3226E which offers 250kbps, this model guarantees 1Mbps operation. It shares the same pinout and core architecture as other members of the family but differs in guaranteed data rate specifications.

Replacement Considerations

The MAX3227EEAE+T serves as a direct alternative utilizing SSOP-16 packaging instead of TSSOP-16. Other family members like the MAX3225E offer similar features but provide two drivers and receivers rather than one.
