MAX3222EWN+T

Overview

The MAX3222EWN+T is a low-power, true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 3.0V to 5.5V supply and features two drivers and two receivers for full-duplex communication. The device utilizes an internal dual charge pump requiring only four 0.1µF external capacitors. It guarantees data rates up to 120kbps with worst-case loads, typically reaching 235kbps. The E suffix indicates an extended temperature range of -40°C to +85°C. Packaged in an 18-pin Wide SOIC (WSOIC), it includes shutdown control to reduce supply current to less than 1µA.

Feature Summary

Integrated dual charge pump eliminates the need for bipolar ±12V supplies
Shutdown mode reduces power consumption for battery-powered applications
Compatible with industry-standard MAX242 pinouts and functionality

Applications

Battery-powered equipment
Hand-held devices
Peripherals
Datacom equipment

Procurement Notes

Verify the ordering suffix 'T' corresponds to tape-and-reel packaging rather than tube packaging when sourcing components. Confirm that the 'E' designation matches the required -40°C to +85°C operating temperature range for the specific application environment. Ensure the 18-pin WSOIC footprint aligns with the PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this component for designs requiring compatibility with legacy MAX242/MAX232 interfaces while utilizing a single low-voltage supply. The MAX3222 is suitable for systems needing two channels of RS-232 communication. Consider the thermal resistance characteristics of the WSOIC package if high ambient temperatures are expected within the specified operating range.

Part Context

This part belongs to the MAX3222 family of low-power RS-232 transceivers. It shares functional similarities with the MAX3232 but differs in pin configuration and receiver availability. The MAX3222EWN+ variant specifically provides the wide SOIC package option for designers preferring this form factor over TSSOP or SSOP alternatives within the same electrical specification set.
