MAX3226EAAE+T

Overview

The MAX3226EAAE+T is a single-driver, single-receiver RS-232 transceiver from the MAX3226E series. It operates on a +3.0V to +5.5V supply and guarantees a data rate of 250kbps. The device features AutoShutdown Plus technology, achieving a typical supply current of 1μA when inactive. It includes ±15kV ESD protection on all I/O pins and provides a READY output signal. The component is housed in a 16-pin SSOP package and supports an extended industrial temperature range of -40°C to +125°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
• Hand-held devices and peripherals

Procurement Notes

Verify the specific suffix 'AE' corresponds to the 16-SSOP package and the '+T' indicates tape-and-reel packaging. Confirm the 'AA' designation aligns with the -40°C to +125°C extended temperature range requirements for your target environment before finalizing procurement.

Selection Notes

Select this part for applications requiring a single full-duplex channel with low standby power. Ensure the system design accommodates the 250kbps maximum data rate limit. Verify that the 16-SSOP footprint matches the PCB layout constraints and that the extended temperature rating meets environmental specifications.

Part Context

This component belongs to the MAX3224E–MAX3245E family of 3V-powered RS-232 interfaces. Unlike the MAX3227E which offers 1Mbps speeds, the MAX3226E variant is optimized for 250kbps operation. It shares the same AutoShutdown Plus architecture and ESD protection characteristics as its higher-speed counterparts within the Maxim Integrated portfolio.

Replacement Considerations

The MAX3226EEAE+ (tube) serves as a direct pin-compatible alternative differing primarily in shipping packaging rather than electrical function. Other family members like the MAX3227E offer identical pinouts but provide increased data rates up to 1Mbps.
