MAX3232CUE+

Overview

The MAX3232CUE+ is a low-power, true RS-232 transceiver manufactured by Analog Devices (Maxim Integrated). It features two drivers and two receivers with a proprietary low-dropout output stage. The device operates from a single +3.0V to +5.5V supply using a dual charge pump that requires only four 0.1µF external capacitors. It guarantees data rates of 120kbps while maintaining RS-232 output levels, with typical operation up to 235kbps. The component is housed in a 16-pin TSSOP package and supports an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrated dual charge pump eliminates the need for bipolar ±12V supplies
• Compatible with industry-standard MAX232 pinouts and functionality
• Low power consumption suitable for battery-powered applications

Applications

• Battery-Powered Equipment
• Hand-Held Equipment
• Peripherals
• Datacom Equipment

Procurement Notes

Verify the specific suffix 'CUE+' corresponds to the commercial temperature grade (0°C to +70°C) and lead-free packaging status. Confirm the 16-pin TSSOP package dimensions match the design footprint requirements. Ensure the ordering code matches the exact manufacturer part number to avoid functional discrepancies.

Selection Notes

Select this component when interfacing 3.3V or 5V logic systems with RS-232 ports without requiring negative voltage rails. It serves as a direct replacement for the MAX232 in designs needing lower power consumption. Verify that the required data rate does not exceed 235kbps for standard operation.

Part Context

This device belongs to the MAX3222/MAX3232/MAX3237/MAX3241 family of low-power RS-232 transceivers. It shares the same core architecture but differs in channel count and speed capabilities compared to siblings like the MAX3237 or MAX3241.
