MAX236CWG+

Overview

The MAX236CWG+ is a +5V-powered, multichannel RS-232 driver and receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within the commercial temperature range of 0°C to +70°C and utilizes a 24-pin Wide SOIC package. The device integrates dual charge-pump DC-DC voltage converters that generate ±10V from a single +5V supply, eliminating the need for external bipolar power sources. It supports EIA/TIA-232E and V.28/V.24 communication interfaces with a typical data rate of 120kbps and an output voltage swing of ±5V to ±7.5V under standard loading conditions.

Feature Summary

• Integrates dual charge-pump circuitry to convert a single +5V supply into the required ±10V levels for RS-232 operation
• Eliminates the requirement for external bipolar power supplies or additional discrete components
• Supports full-duplex communication compliant with EIA/TIA-232E and V.28/V.24 standards

Applications

• Interface translation between TTL/CMOS logic and RS-232 serial ports
• Multidrop RS-232 network connections
• Portable diagnostic equipment requiring compact serial communication solutions

Procurement Notes

Verify the specific suffix 'CWG+' against the manufacturer's current ordering information to confirm the exact package type and lead-free status. Confirm the operating temperature grade corresponds to the 'C' designation (0°C to +70°C). Ensure compatibility with the 24-pin Wide SOIC footprint during PCB layout verification.

Selection Notes

Select this component when board space is limited and external capacitors are undesirable, as the MAX236 family typically integrates internal capacitors. Verify that the required number of drivers and receivers matches the specific channel count of the MAX236 variant. Ensure the application environment remains within the specified commercial temperature range.

Part Context

This component belongs to the MAX220–MAX249 family of +5V-powered, multichannel RS-232 drivers and receivers. The family offers various configurations in multiple packages to accommodate different channel counts and form factor requirements while maintaining compatibility with standard RS-232 protocols.
