MAX214EWI+T

Drivers, Receivers, Transceivers Overview

The MAX214EWI+T is a +5V RS-232 transceiver providing an 8-line, software-configurable DTE or DCE interface. It operates from a single +5V supply using four 1µF charge-pump capacitors to generate ±10V rails. The device supports data rates up to 116kbps and features a shutdown mode with 20µA current consumption while keeping receivers active. It is housed in a 28-pin Wide SO package and operates within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Eliminates the need for null modem cables through software-selectable DTE/DCE configuration
• Integrates dual charge pumps requiring only four 1µF external capacitors
• Maintains receiver activity during shutdown mode for ring indicator detection

Drivers, Receivers, Transceivers Applications

• AT-Compatible Laptop Computers
• AT-Compatible Desktop Computers
• Modems, Printers, and Other Peripherals

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'EWI' confirms the wide operating temperature range (-40°C to +85°C) and the 28-pin Wide SOIC package type. Confirm RoHS compliance status as indicated by the '+' designation. Ensure the source document matches the official Maxim Integrated datasheet for accurate pinout and electrical specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single IC must support both DTE and DCE serial port configurations without hardware changes. It is suitable for applications requiring low power consumption via shutdown mode while maintaining the ability to detect external signals like ring indicators. Verify that the system can accommodate the required four 1µF capacitors for the charge pump circuitry.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX214 family of programmable RS-232 transceivers. It is designed to replace traditional multi-chip solutions by integrating all necessary drivers, receivers, and voltage converters into a single package. The EWI variant specifically denotes the extended industrial temperature range and surface-mount packaging.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other MAX214 variants such as MAX214CWI+T for commercial temperature ranges. Cross-family alternatives may require checking pin compatibility and ensuring equivalent charge pump capacitor requirements are met.
