MAX1406EWE

Drivers, Receivers, Transceivers Overview

The MAX1406EWE is a ±15kV ESD-protected, EMC-compliant RS-232 transceiver featuring three transmitters and three receivers. It operates on a +4.5V to +5.5V VCC supply and requires dual ±10.8V to ±13.2V supplies for RS-232 levels. The device guarantees data rates up to 230kbps with a typical ICC of 1mA. It utilizes a 16-pin Wide SO package and supports an operating temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Enhanced electrostatic discharge protection rated at ±15kV Human Body Model and ±8kV IEC1000-4-2 Contact Discharge
• Pin and functionally compatible with the industry-standard MC145406
• Flow-through pinout configuration simplifies PCB layout

Drivers, Receivers, Transceivers Applications

• Telecommunications equipment
• Modems
• Printers
• Instruments meeting IEC1000-4-2 standards

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E' indicates the extended industrial temperature range (-40°C to +85°C) compared to the commercial 'C' variant. Confirm the 'W' suffix corresponds to the 16-pin Wide SOIC package dimensions. Ensure the ordering code matches the exact manufacturer part number to avoid functional or packaging discrepancies.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust ESD immunity without external protection diodes. It is suitable for applications needing three independent RS-232 channels. Verify that the system can provide the necessary dual voltage rails for proper RS-232 signal generation.

Drivers, Receivers, Transceivers Part Context

This device belongs to the Maxim Integrated MAX1406 family of RS-232 interface ICs. It serves as a direct replacement for legacy designs using the MC145406 while offering superior ESD performance. The series includes variants with different temperature ratings and package options to suit various environmental constraints.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX1406EWE is pin-compatible with the MC145406. Other MAX1406 variants include MAX1406CWE (commercial temperature) and MAX1406EAE (SSOP package). Verify package footprint compatibility before substitution.
