MAX233ACWP+TG36

Overview

The MAX233ACWP+TG36 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 the need for external components or bipolar ±12V supplies. The device provides two drivers and two receivers with full-duplex communication capability. Key electrical parameters include a data rate of 120kbps, propagation delay of 0.25µs, and 15kV ESD protection. It is housed in a 20-pin Wide SOIC package and supports an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrated charge pump eliminates the need for external capacitors or bipolar power supplies
• Single +5V supply operation simplifies system design
• Internal capacitors reduce printed circuit board space requirements
• Provides 15kV ESD protection for robust signal integrity

Applications

• Interface translation between TTL/CMOS logic and RS-232 standards
• Multidrop RS-232 network connections
• Portable diagnostics equipment requiring compact form factors

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific ordering suffixes that may indicate packaging variations. Ensure the supplier provides valid traceability documentation matching the part number MAX233ACWP+TG36.

Selection Notes

Select this component when board space is critical due to its integrated capacitor design. It is suitable for applications requiring single-supply operation without generating negative voltages externally. Verify that the required data rate does not exceed 120kbps and that the operating environment stays within the commercial temperature range.

Part Context

This part belongs to the MAX220–MAX249 family of +5V-powered multichannel RS-232 drivers and receivers. The 'A' suffix typically denotes tighter electrical specifications compared to standard variants, while 'C' indicates the commercial temperature range. The 'WP' suffix specifies the 20-pin Wide SOIC package format.

Replacement Considerations

Compatible substitutes within the same family include MAX233AEWP+TG36 for extended temperature ranges (-40°C to +85°C). Other pin-compatible options like MAX232 or MAX235 require verification of driver/receiver counts and control pin configurations.
