MAX214EPI+

Drivers, Receivers, Transceivers Overview

The MAX214EPI+ is a +5V RS-232 transceiver in a 28-pin plastic dual-in-line package. It provides an 8-line, software-configurable interface supporting both Data Terminal Equipment (DTE) and Data Circuit-Terminating Equipment (DCE) modes via the DTE/DCE control pin. The device operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 116kbps. It incorporates a dual charge-pump converter requiring four 1µF capacitors. A shutdown mode reduces supply current to typically 20µA while keeping receivers active for ring indicator detection. The component functions across an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Software-selectable DTE or DCE configuration eliminates the need for null modem cables
• Integrated dual charge-pump voltage converter generates required RS-232 voltages using only 1µF capacitors
• Low-power shutdown mode with active receivers for continuous signal monitoring

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 EPI confirms the 28-pin Plastic DIP package and the extended industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status as indicated by the '+' designation in the ordering information. Ensure the source documentation matches the official Maxim Integrated datasheet specifications for electrical characteristics and pin configurations.

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 standby power consumption due to the shutdown feature. Verify that the system can accommodate the external 1µF charge-pump capacitors and that the 116kbps data rate meets the communication requirements.

Drivers, Receivers, Transceivers Part Context

The MAX214EPI+ belongs to the MAX214 family of +5V RS-232 transceivers manufactured by Analog Devices Inc./Maxim Integrated. This series is designed to provide complete RS-232 interfaces with programmable DTE/DCE functionality. The EPI variant specifically denotes the plastic DIP packaging option with industrial temperature rating, distinguishing it from wide SOIC or commercial temperature variants.
