MAX241EAI+

Overview

The MAX241EAI+ is a +5V-powered, multichannel RS-232 transceiver from the Analog Devices/MAXIM MAX220–MAX249 family. It integrates four drivers and five receivers for full-duplex communication at data rates up to 120 kbps. The device operates on a single +5V supply (4.5V to 5.5V) using an internal charge pump to generate ±10V rails. It features a shutdown mode with 5μW power consumption and includes integrated capacitors to save board space. The component is housed in a 28-pin SSOP package and supports an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated charge-pump circuitry eliminates the need for external bipolar ±12V supplies
• Built-in capacitors reduce printed circuit board space requirements
• Low-power shutdown mode reduces current consumption to 5μW
• Single +5V supply operation enables simplified system design

Applications

• Interface translation between TTL/CMOS logic and RS-232 standards
• Multidrop RS-232 network connections
• Portable diagnostic equipment requiring low power consumption

Procurement Notes

Verify the specific ordering suffix 'EAI+' against official manufacturer documentation to confirm the exact package type and temperature rating. Ensure that the selected variant matches the required thermal performance and physical footprint for the target application before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring multiple RS-232 channels without external voltage inversion components. Consider the 28-pin SSOP package constraints and verify that the 120 kbps data rate meets the application's throughput requirements. Evaluate the shutdown functionality if power management during idle states is critical.

Part Context

This part belongs to the MAX220–MAX249 series of line drivers and receivers designed for EIA/TIA-232E and V.28/V.24 interfaces. The series offers various configurations of drivers and receivers in different packages to accommodate diverse space and channel count requirements while maintaining single-supply operation.

Replacement Considerations

Compatible alternatives within the same family include the MAX241ECWI+ and MAX241EWI+. Verify pin compatibility and electrical specifications before substitution.
