MAX214CWI+

Drivers, Receivers, Transceivers Overview

The MAX214CWI+ is a +5V RS-232 transceiver featuring an 8-line, software-configurable interface for DTE or DCE port applications. It operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 116kbps. The device incorporates dual charge-pump converters requiring four 1µF capacitors to generate the necessary ±10V levels. It includes three drivers and five receivers housed in a 28-pin Wide SO package with an operating temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Eliminates the need for null modem cables through software-selectable DTE/DCE configuration
• Integrates dual charge-pump voltage converters utilizing only 1µF external capacitors
• Provides a low-power shutdown mode that maintains active receiver functionality 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 'W' indicates the Wide SOIC package variant rather than the Plastic DIP option. Confirm the 'C' designation aligns with the commercial temperature range requirements for your deployment environment. Ensure the component meets RoHS standards as indicated by the '+' suffix before finalizing procurement specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single IC must support both DTE and DCE configurations without hardware modifications. It is suitable for systems requiring minimal external capacitance due to the integrated charge pumps. Consider the 116kbps speed limit and ensure the application does not require higher baud rates or extended industrial temperature ranges beyond the specified limits.

Drivers, Receivers, Transceivers Part Context

This part belongs to the Maxim Integrated MAX214 series of programmable RS-232 transceivers. It serves as a complete interface solution for serial communication ports, replacing discrete transistor-based designs.
