MAX225CWI+G36

Overview

The MAX225CWI+G36 is a +5V-powered, multichannel RS-232 driver and receiver integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.75V to 5.25V and supports data rates up to 120 kbps. The device features five drivers and five receivers with an input voltage operating range of ±25V. It utilizes an internal charge-pump circuitry to generate the necessary voltages for RS-232 communication without requiring external bipolar supplies.

Feature Summary

• Integrated charge pump eliminates the need for external components or bipolar power supplies
• Enables single-supply operation from a +5V source
• Provides shutdown mode for reduced power consumption

Applications

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

Procurement Notes

Verify the component against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Ensure that the ordering suffix corresponds to the required temperature grade and packaging format. Cross-reference the part number with authorized distributors to validate authenticity and current production status before procurement.

Selection Notes

Select this component when board space is critical due to its integrated capacitor design. It is suitable for applications requiring multiple channels of RS-232 communication powered solely by a +5V supply. Consider the specific package options and temperature ranges available in the family when finalizing the design.

Part Context

This part belongs to the MAX220–MAX249 family of line drivers and receivers designed for EIA/TIA-232E and V.28/V.24 interfaces. The family offers various configurations with different numbers of drivers and receivers, catering to diverse interface requirements while maintaining low power consumption and compact form factors.

Replacement Considerations

Compatible substitutes within the same family include other MAX22x/MAX24x variants with matching channel counts and package types. Verify functional equivalence regarding control pin configurations and electrical characteristics before substitution.
