MAX214CWI+T

Overview

The MAX214CWI+T is a +5V-powered, multichannel RS-232 transceiver housed in a 28-pin Wide SOIC package. It provides an 8-line interface with software-configurable DTE or DCE operation via the DTE/DCE control pin. The device operates from a single +5V supply using integrated 1µF charge-pump capacitors to generate internal voltages. It supports data rates up to 116kbps and features a shutdown mode that reduces supply current to 20µA while keeping receivers active for ring indicator detection.

Feature Summary

• Software-configurable DTE or DCE serial port eliminates the need for null modem cables
• Integrated 1µF charge-pump capacitors enable single-supply +5V operation
• Shutdown mode reduces power consumption while maintaining active receiver functionality

Applications

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

Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range of 0°C to +70°C. Confirm the '+T' designation corresponds to reel packaging as specified in the ordering information. Ensure compatibility with existing +5V logic levels and RS-232 signal requirements before integration.

Selection Notes

Select this component when a single IC must handle both DTE and DCE configurations without hardware changes. It is suitable for applications requiring low standby power due to the shutdown feature. Verify that the 116kbps maximum data rate meets system timing constraints and that the 28-pin Wide SOIC package fits the PCB layout.

Part Context

This part belongs to the MAX214 family of programmable RS-232 transceivers. The 'C' suffix denotes the commercial operating temperature range, distinguishing it from the 'E' suffix variant which supports extended temperatures. The device integrates all necessary components for RS-232 communication on a single +5V supply.
