ADM241LJRS-REEL

Overview

The ADM241LJRS-REEL is a CMOS RS-232 transceiver from Analog Devices, operating on a single 5 V supply. It integrates four drivers and five receivers within a 28-pin SSOP package. The device supports data rates up to 120 kbps and generates internal ±10 V supplies using external 1 µF capacitors. It features low power shutdown mode with current consumption of ≤1 µA and includes enable functionality for receiver outputs. The component meets EIA-232-E specifications and operates across commercial temperature ranges.

Feature Summary

• Integrates dual charge pump converters to generate required voltage levels from a single 5 V source
• Includes dedicated control pins for enabling receiver outputs and activating low power shutdown states
• Provides Schmitt trigger inputs on receivers to ensure noise immunity during signal transitions

Applications

• Battery-powered equipment requiring minimal power dissipation
• Microprocessor systems sharing common data lines
• Industrial instruments and peripherals

Procurement Notes

Verify the J suffix indicates the commercial temperature range variant. Confirm the REEL suffix matches the required tape and reel packaging format for automated assembly processes. Ensure the SSOP package dimensions align with the target PCB footprint design constraints.

Selection Notes

Select this component when a high channel count with integrated shutdown control is necessary. Compare against the ADM236L if fewer drivers are sufficient. Verify that the 120 kbps speed meets system requirements. Check thermal dissipation limits for the specific SSOP package configuration in the final enclosure.

Part Context

This part belongs to the ADM2xxL family of enhanced CMOS RS-232 interfaces. It serves as an upgrade to older AD2xx series components, offering lower power consumption and compatibility with smaller capacitors. The ADM241L specifically targets applications needing multiple transmitter and receiver channels with advanced power management capabilities.

Replacement Considerations

ADM236L offers similar functionality but with only three receivers instead of five.
