MAX214EWI+

Drivers, Receivers, Transceivers Overview

The MAX214EWI+ is a +5V RS-232 transceiver providing an 8-line, software-configurable interface for DTE or DCE ports. It operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 116kbps in normal mode, with a guaranteed minimum output voltage swing of ±5.0V. The device features a shutdown mode reducing supply current to typically 20µA while keeping receivers active. It utilizes four 1µF charge-pump capacitors to generate internal voltages and is housed in a 28-pin Wide SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Software-configurable DTE/DCE port eliminates the need for null modem cables
• Integrated dual charge-pump voltage converter requires only 1µF external capacitors
• Low-power shutdown mode maintains receiver activity 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+' corresponds to the -40°C to +85°C temperature range and 28-pin Wide SOIC package. Confirm RoHS compliance status as indicated by the '+' designation. Ensure the source document matches the official Maxim Integrated datasheet for accurate electrical specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single IC must support both DTE and DCE configurations via software control. It is suitable for applications requiring low standby power consumption with active receiver monitoring. Verify that the system can accommodate the required 1µF charge-pump capacitors and operates within the specified +5V supply constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX214 family of programmable RS-232 transceivers. The 'E' suffix denotes the extended industrial temperature range (-40°C to +85°C), while 'WI+' indicates the 28-pin Wide Small Outline package with lead-free/RoHS compliance. It serves as a direct replacement for fixed-function RS-232 interfaces where cable swapping was previously necessary.
