MAX3212EAI+T

Overview

The MAX3212EAI+T is a true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 28-SSOP surface-mount package. It integrates three drivers and five receivers for full-duplex communication. The device operates on a single 3V to 5.5V power supply and supports data rates up to 1Mbps. Key electrical characteristics include 15kV ESD protection per IEC 61000-4-2 standards and a shutdown mode that reduces supply current to below 1µA. The operational temperature range spans from -40°C to +85°C.

Feature Summary

• Integrates three independent drivers and five independent receivers within a single package
• Provides robust electrostatic discharge protection rated at 15kV according to IEC 61000-4-2
• Features an ultra-low power shutdown mode significantly reducing standby consumption

Applications

• Industrial serial communication equipment requiring reliable RS-232 connectivity
• Portable battery-powered instruments utilizing low-voltage operation
• Modems and handheld terminals needing high ESD immunity

Procurement Notes

Verify the specific suffix 'EAI' corresponds to the SSOP-28 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the procurement channel provides valid traceability for the Analog Devices or Maxim Integrated brand. Cross-reference the complete part number against distributor databases to confirm availability and lead times.

Selection Notes

Select this component for designs requiring multiple receiver inputs alongside standard driver outputs. The wide 3V to 5.5V supply range accommodates various logic levels without external level shifting. Consider the 28-SSOP footprint for space-constrained PCB layouts. Evaluate the 1Mbps speed capability against system timing requirements to ensure adequate performance margins.

Part Context

This device belongs to the MAX32xx series of true RS-232 transceivers designed for low-power applications. It complements other variants like the MAX3241 by offering a different configuration of drivers and receivers. The series emphasizes ease of use with minimal external capacitor requirements while maintaining industrial-grade reliability and protection specifications.

Replacement Considerations

MAX3241EEAI+T offers similar functionality with a 3-driver/5-receiver configuration in the same SSOP-28 package.
