MAX1406EWE+T

Drivers, Receivers, Transceivers Overview

The MAX1406EWE+T is a ±15kV ESD-protected, EMC-compliant RS-232 transceiver featuring three transmitters and three receivers. It supports data rates up to 230kbps with a guaranteed performance at 120kbps under worst-case load conditions (3kW, 1000pF). The device operates on a single +5V supply for logic (VCC: 4.5V to 5.5V) and dual supplies for RS-232 levels (VDD: +10.8V to +13.2V; VSS: -10.8V to -13.2V). Supply currents are typically 185µA for IDD and ISS, and 2mA for ICC. It includes ±15kV Human Body Model and ±15kV IEC1000-4-2 Air-Gap ESD protection, latchup-free operation, and hysteresis of 650mV on receiver inputs. The component is housed in a 16-pin Wide SO package.

Drivers, Receivers, Transceivers Feature Summary

• Enhanced electrostatic discharge protection meeting stringent European EMC requirements without external components
• Pin and functionally compatible with industry-standard MC145406 for direct design upgrades
• Flow-through pinout architecture simplifies PCB layout and signal routing
• Latchup-free performance ensures continued operation following high-energy ESD events

Drivers, Receivers, Transceivers Applications

• Telecommunications equipment
• Modems
• Printers
• Instruments requiring IEC1000-4-2 compliance

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +85°C) compared to the commercial 'C' variant. Confirm the 'W' suffix corresponds to the 16-pin Wide SO package. Ensure the '+T' designation matches the required reel packaging format for surface-mount assembly processes.

Drivers, Receivers, Transceivers Selection Notes

Select this component when existing designs utilize the MC145406 but require improved ESD robustness and EMC compliance. It is suitable for applications needing three independent RS-232 channels with low power consumption. Verify that the system can provide the necessary dual voltage rails (+12V/-12V typical) alongside the standard +5V logic supply.

Drivers, Receivers, Transceivers Part Context

The MAX1406 series addresses the need for robust serial communication interfaces in environments prone to static discharge. The 'E' grade extends operational reliability into industrial temperature ranges, while the Wide SO package offers a compact footprint relative to traditional DIP options. This part serves as a drop-in replacement for legacy MC145406 implementations.
