ADM241LARSZ-REEL

Overview

The ADM241LARSZ-REEL is a single-supply CMOS RS-232 transceiver from Analog Devices, housed in a 28-pin SOIC package. It operates on a single 5 V power supply and integrates internal charge pumps to generate the required ±10 V levels for EIA-232-E compliance. The device features four drivers and five receivers with a data rate of 120 kbps. It includes low power shutdown (≤1 µA) and enable functions for system control. Operating temperatures range from -40°C to +85°C.

Feature Summary

• Integrates dual charge pump voltage converters to generate ±10 V supplies from a single 5 V input
• Features low power shutdown mode reducing dissipation to less than 5 µW
• Includes receiver enable function for high impedance state control

Applications

• Battery-powered equipment requiring low standby current
• Industrial instruments with RS-232 communication interfaces
• Modems and peripheral devices operating on single 5 V logic

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the REEL designation aligns with automated assembly requirements. Cross-reference the manufacturer part number against official distributor catalogs to ensure authenticity and correct revision level before finalizing procurement orders.

Selection Notes

Select this component when a single 5 V supply is available but standard RS-232 voltage levels are required. The ADM241L is suitable for designs needing multiple receiver inputs and low power consumption. Ensure external capacitors meet the specified voltage ratings and capacitance values for proper charge pump operation.

Part Context

This part belongs to the ADM2xxL family of line drivers and receivers designed for EIA-232-E applications. It serves as an enhanced upgrade to the AD2xx series, offering lower power consumption and faster slew rates. The ADM241L specifically provides a higher count of receivers compared to similar models like the ADM236L.
