MAX236CWG

Overview

The MAX236CWG 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 4.5V to 5.5V and supports data rates up to 160kbps. The device features an internal dual charge-pump DC-DC converter that generates ±10V from the single +5V supply, eliminating the need for external bipolar power sources. It provides two drivers and two receivers with TTL/CMOS-compatible inputs and outputs. The component is housed in a 16-pin Wide SOIC package and is rated for operation across a temperature range of 0°C to +70°C.

Feature Summary

• Integrated charge pump eliminates the need for external capacitors or bipolar supplies
• Single +5V supply operation simplifies system design
• TTL and CMOS logic compatibility ensures broad interface support

Applications

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

Procurement Notes

Verify the specific suffix 'CWG' against official manufacturer documentation to confirm exact pinout, lead finish, and temperature grade specifications. Confirm current production status as older Maxim Integrated products may have been discontinued or superseded by newer revisions.

Selection Notes

Select this component when board space is critical due to its integrated capacitor architecture. Ensure the application environment remains within the specified commercial temperature range of 0°C to +70°C. Verify that the required data rate does not exceed the maximum supported speed for the selected load conditions.

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 channel configurations and packages to address different space and performance requirements in serial communication systems.

Replacement Considerations

Direct replacements include other members of the MAX220-MAX249 family such as the MAX232 or MAX233, provided they match the required channel count and package dimensions. Verify functional equivalence regarding control pins and electrical characteristics before substitution.
