MAX241EEAI

Overview

The MAX241EEAI is a single-supply RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a +4.5V to +5.5V supply and features four drivers and five receivers. The device supports data rates up to 120kbps with ±15kV ESD protection on driver outputs and receiver inputs. It includes an integrated charge pump requiring four external 1μF capacitors for voltage conversion. The EE suffix indicates an extended temperature range of -40°C to +85°C, and the AI suffix denotes a 28-pin SSOP package.

Feature Summary

• Integrated high ±15kV HBM ESD protection on RS-232 I/O pins
• Single +5V supply operation via internal charge pump circuitry
• Low-power shutdown mode reducing supply current to 1μA typical
• Receiver enable control for wire-OR port connection

Applications

• Battery-powered equipment
• Hand-held equipment
• Portable diagnostics equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature rating. Confirm RoHS compliance status through the supplier or manufacturer datasheet before procurement. Ensure the component source is authorized to avoid counterfeit parts.

Selection Notes

Select this component when designing systems requiring multiple RS-232 channels from a single +5V rail. The MAX241E provides four drivers and five receivers, suitable for complex interface designs. Verify that the application requires the extended temperature range indicated by the 'EE' suffix and the surface-mount SSOP package associated with the 'AI' suffix.

Part Context

The MAX241E belongs to the MAX202E–MAX213E family of RS-232 transceivers. This family shares common architecture including integrated charge pumps and ESD protection. The MAX241E specifically offers a higher channel count compared to devices like the MAX232E, providing four drivers and five receivers in a 28-pin package.

Replacement Considerations

The MAX241EWI+ is a pin-compatible alternative in a 28-pin SOIC package. Both devices share identical electrical characteristics and functionality. Selection between these variants depends primarily on the required surface-mount package footprint.
