MAX234EPE+

Overview

The MAX234EPE+ is a +5V-powered, multichannel RS-232 line driver/receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 120kbps. The device features four drivers and zero receivers, providing full-duplex communication capabilities. It utilizes an integrated charge pump circuit to generate the necessary internal voltages from a single +5V supply, eliminating the need for external bipolar power sources. The component is housed in a 16-pin Wide SOIC package and is rated for operation across an extended temperature range of -40°C to +85°C.

Feature Summary

• Integrated charge pump circuitry eliminates the requirement for external bipolar ±12V power supplies, enabling simplified single-supply system designs.

Applications

• Interface translation between TTL/CMOS logic levels and RS-232 standards
• Multidrop RS-232 network implementations
• Portable diagnostics equipment requiring low-power serial communication

Procurement Notes

Verify the specific suffix 'EPE+' against official manufacturer documentation to confirm the exact package type (Wide SOIC) and industrial temperature rating (-40°C to +85°C). Ensure that ordering information aligns with current production status and availability constraints defined by Analog Devices or Maxim Integrated.

Selection Notes

Select this component when a design requires multiple transmitter outputs without receiver inputs on a single chip. Verify that the required data rate does not exceed 120kbps and that the application environment falls within the specified -40°C to +85°C operating temperature range.

Part Context

This part belongs to the MAX220–MAX249 family of +5V-powered, multichannel RS-232 drivers and receivers. This series is designed for EIA/TIA-232E and V.28/V.24 communications interfaces, particularly where space savings and single-supply operation are critical requirements.
