MAX232CWE-TG074

Overview

The MAX232CWE-TG074 is an RS-232 interface integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V power supply and includes internal charge pumps to generate the required voltage levels for EIA/TIA-232E communication without external components. The device features two drivers and two receivers, supporting full-duplex data transmission at rates up to 120 kb/s. It is housed in a 16-pin SO-Wide package designed for surface mount technology. The operating supply voltage ranges from 4.5 V to 5.5 V, with a typical operating current of 10 mA. The component functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrates dual drivers and dual receivers for complete RS-232 transceiver functionality
• Utilizes internal charge pumps to eliminate the need for external voltage generation components
• Supports full-duplex communication compliant with EIA/TIA-232E standards

Applications

• EIA/TIA-232E communications interfaces
• V.28/V.24 serial port connections
• Modem interfacing applications

Procurement Notes

Verify the specific suffix TG074 against official manufacturer documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with standard SO-Wide-16 footprints during PCB layout. Cross-reference the part number with Analog Devices databases to validate current production status and regional availability constraints before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring standard RS-232 signaling with a single +5V supply. It is suitable for applications where board space is limited due to the absence of external capacitors for charge pumping. Consider the 120 kb/s data rate limit and commercial temperature range when evaluating suitability for high-speed or industrial environments.

Part Context

This part belongs to the MAX232 family of multichannel RS-232 drivers and receivers. The family is designed for applications where ±12V power supplies are unavailable. The MAX232CWE variant specifically denotes the commercial temperature grade and wide SOIC package configuration within the broader Maxim Integrated interface IC portfolio.
