MAX3241CAI

Overview

The MAX3241CAI is a true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 28-pin SSOP package. It operates from a single +3.0V to +5.5V supply and features three drivers and five receivers. The device guarantees data rates up to 120kbps while maintaining standard RS-232 output levels. It utilizes a dual charge pump requiring only four 0.1µF external capacitors. The operating temperature range for the 'C' suffix variant is 0°C to +70°C.

Feature Summary

• Integrated dual charge pump eliminates the need for bipolar ±12V supplies
• Always-on complementary receiver outputs enable monitoring without forward biasing protection diodes
• Low-power shutdown mode reduces supply current to less than 1µA

Applications

• Battery-powered equipment
• Hand-held equipment
• Peripherals
• Datacom equipment

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the exact package type and temperature rating. Confirm RoHS compliance status through the supplier's certification documents. Ensure the component source is an authorized distributor to guarantee authenticity and traceability.

Selection Notes

Select this component when interfacing with RS-232 standards using a single low-voltage supply. The MAX3241 is suitable for applications requiring multiple receiver inputs and driver outputs. Verify that the required operating temperature falls within the commercial range of 0°C to +70°C for this specific part number.

Part Context

This component belongs to the MAX3222/MAX3232/MAX3237/MAX3241 family of low-power RS-232 transceivers. It shares core architecture with other members but provides a distinct configuration of three drivers and five receivers. The family is characterized by its ability to operate from a single supply voltage using minimal external capacitance.
