MAX241ECAI+T

Overview

The MAX241ECAI+T is a single-supply RS-232 transceiver from the MAX202E–MAX213E family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a +5V supply (4.5V to 5.5V) and features four drivers and five receivers. The device supports data rates up to 120kbps with ±15kV ESD protection on inputs and outputs. It includes an integrated charge pump requiring four 1μF external capacitors. The component is housed in a 28-pin SSOP package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrated high ±15kV HBM ESD protection for robust operation in harsh environments
• Single +5V supply operation enabled by internal charge-pump circuitry
• Low-power shutdown mode significantly reduces supply current consumption
• Receiver enable control allows wire-OR connection of multiple ports

Applications

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

Procurement Notes

Verify the specific suffix 'CAI' corresponds to the commercial temperature range (0°C to +70°C) and SSOP-28 package configuration. Confirm that the '+T' designation indicates tape-and-reel packaging if required for automated assembly processes. Ensure compatibility with the required 1μF charge-pump capacitor values specified in the datasheet.

Selection Notes

Select this component when designing systems requiring four transmit and five receive channels on a single +5V rail. It is suitable for applications needing high ESD immunity without external protection components. Consider the 1μF capacitor requirement compared to other family members using 0.1μF capacitors. Verify that the 120kbps maximum data rate meets the system's communication speed requirements.

Part Context

This part belongs to the MAX241E series of RS-232 transceivers designed for single-supply applications. It shares architectural similarities with the MAX232E but offers increased channel count with four drivers and five receivers. The 'E' suffix denotes enhanced ESD protection capabilities compared to standard versions. It is part of a broader family including MAX202E through MAX213E devices.

Replacement Considerations

The MAX241EWI+ is a pin-compatible alternative available in a wide SOIC-28 package with an extended industrial temperature range (-40°C to +85°C). Designers must verify thermal performance and package footprint differences when substituting between SSOP and SOIC variants.
