MAX233AEWP+G36

Overview

The MAX233AEWP+G36 is a dual RS-232 transceiver from the MAX220–MAX249 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply (4.75V to 5.25V) and features integrated charge-pump circuitry with internal capacitors, eliminating external components. The device provides two drivers and two receivers in a 20-pin Wide SOIC package. Key electrical parameters include a data rate of 120kbps, propagation delay of 0.25µs, and 1mA operating current. It supports full-duplex communication within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated charge pump eliminates need for bipolar ±12V supply
• Internal capacitors reduce printed circuit board space requirements
• Single +5V supply operation capability
• Shutdown mode reduces power consumption

Applications

• Interface translation between TTL/CMOS and RS-232 standards
• Multidrop RS-232 networks
• Portable diagnostics equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for End-of-Life notices prior to procurement. Ensure ordering suffixes match required packaging and temperature grades. Validate datasheet revisions against current production specifications.

Selection Notes

Select this component when board space is critical due to integrated capacitors. Suitable for applications requiring single-supply RS-232 communication without external charge-pump components. Verify that the 120kbps data rate meets system requirements. Consider the 20-pin Wide SOIC package constraints for PCB layout design.

Part Context

Part of the MAX220–MAX249 family of +5V-powered multichannel RS-232 drivers/receivers. Designed for EIA/TIA-232E and V.28/V.24 interfaces where ±12V supplies are unavailable. Offers various package options and temperature ranges across the family lineup.

Replacement Considerations

Compatible replacements within the same family include MAX233A variants with different temperature grades or packages. Verify pin compatibility and electrical specifications before substitution.
