ADM241LJRSZ

Overview

The ADM241LJRSZ is a CMOS RS-232 transceiver from the ADM2xxL family, designed for EIA-232-E and V.28 interfaces using a single 5 V supply. It integrates four drivers and five receivers with on-board dc-to-dc converters generating ±10 V levels. The device supports data rates up to 120 kbps and features low power shutdown (≤1 µA) and an active-low enable input. It operates within a commercial temperature range of 0°C to +70°C and utilizes a 28-pin SSOP package.

Feature Summary

• Integrates internal charge pump voltage converters requiring only small external capacitors
• Features low power shutdown mode reducing dissipation to less than 5 µW
• Includes receiver outputs that can be disabled via an active-low enable pin

Applications

• Battery-powered equipment
• Computers and peripherals
• Modems and printers

Procurement Notes

Verify the J suffix indicates the commercial temperature grade (0°C to +70°C). Confirm the RSZ suffix corresponds to the RoHS-compliant SSOP package. Cross-reference the specific ordering code with Analog Devices documentation to ensure compatibility with existing board layouts.

Selection Notes

Select this component when a single 5 V supply is available but standard RS-232 voltage levels are required. The integrated shutdown and enable functions make it suitable for systems needing power management or bus sharing. Ensure the application does not require industrial temperature ratings, as this variant is limited to commercial grades.

Part Context

This part belongs to the ADM2xxL enhanced upgrade series, offering lower power consumption and faster slew rates compared to the legacy AD2xx family. It shares architectural similarities with the ADM236L but provides additional receiver channels. The device is manufactured by Analog Devices Inc.

Replacement Considerations

ADM236L: Offers similar functionality but with three receivers instead of five.
