MAX233AEWP+TG36

Overview

The MAX233AEWP+TG36 is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply and features integrated charge-pump circuitry to generate internal ±10V rails, eliminating the need for external bipolar supplies or discrete capacitors. The device provides two drivers and two receivers with full-duplex communication capabilities. It supports data rates up to 120kbps and includes a shutdown mode that reduces power consumption significantly. The component is housed in a 20-pin Wide SOIC package and is rated for an industrial operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated charge pump eliminates the need for external capacitors
• Single +5V supply operation without requiring bipolar voltage sources
• Shutdown mode enables significant power reduction

Applications

• Interface translation between TTL/CMOS logic and RS-232 standards
• Multidrop RS-232 network connections
• Portable diagnostic equipment requiring low power consumption

Procurement Notes

Verify the specific suffix 'TG36' against official manufacturer documentation to confirm tape-and-reel packaging details. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Check for obsolescence notices from Analog Devices regarding this specific part number variant before finalizing procurement plans.

Selection Notes

Select this component when board space is critical due to the absence of external capacitors. Ensure the application requires only two channels of RS-232 communication. Verify that the system operates within the specified +5V supply tolerance and meets the required data rate limits for reliable signal integrity.

Part Context

This device belongs to the MAX220–MAX249 family of line drivers and receivers designed for EIA/TIA-232E interfaces. The MAX233 variant specifically integrates capacitors internally, distinguishing it from models like the MAX232 which require external components. This integration simplifies PCB layout and reduces overall system footprint.

Replacement Considerations

Direct replacements include other members of the MAX220-MAX249 family such as the MAX232A or MAX233A, provided they match the required package type and temperature grade. Verify pin compatibility and electrical specifications before substituting.
