MAX233ACWP+G36

Overview

The MAX233ACWP+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 for full-duplex communication at data rates up to 120kbps. 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 bipolar ±12V supplies
• Internal capacitors reduce printed circuit board space requirements
• Single +5V supply operation simplifies power design

Applications

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

Procurement Notes

Verify the specific suffix G36 against official documentation to confirm lead-free status and RoHS compliance. Confirm that the AC designation strictly limits the operating temperature to the commercial range of 0°C to +70°C. Ensure the Wide SOIC package dimensions match the target footprint constraints.

Selection Notes

Select this component when board space is critical due to its integrated capacitor design. It is suitable for applications requiring only two channels of RS-232 communication. Verify that the system environment remains within the 0°C to +70°C commercial temperature range specified for the AC grade.

Part Context

This part belongs to the MAX220–MAX249 family of +5V-powered multichannel RS-232 drivers and receivers. The family offers various channel counts and packages. The MAX233 specifically integrates capacitors internally, distinguishing it from parts requiring external capacitors.

Replacement Considerations

The MAX232A is a functional equivalent within the same family but requires external capacitors. Other family members like the MAX233E offer extended temperature ranges.
