ADM241LAR

Overview

The ADM241LAR is a CMOS RS-232 transceiver designed for single 5 V power supply operation. It integrates four drivers and five receivers, supporting full-duplex communication at data rates up to 120 kbps. The device utilizes internal charge pumps to generate ±10 V supplies from the 5 V input, eliminating the need for external dual-voltage sources. Key features include a low-power shutdown mode with current consumption below 1 µA and an enable function for receiver output control. It meets EIA-232-E specifications with ±9 V output swings and ±30 V receiver input protection.

Feature Summary

Integrates internal DC-to-DC converters to operate from a single 5 V supply
Features low-power shutdown mode for battery-powered applications
Includes enable input for high-impedance receiver output control

Applications

Battery-powered computers and portable equipment
Modems and printers requiring RS-232 interfaces
Instruments and peripherals with limited power availability

Procurement Notes

Verify the specific suffix 'L' indicates the commercial temperature range variant when sourcing. Confirm package type matches design requirements as multiple packages are available within the family. Check manufacturer documentation for any recent revisions or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a single 5 V supply is available but RS-232 voltage levels are required. The ADM241LAR is suitable for designs needing multiple receiver inputs (five) and driver outputs (four). Ensure the application benefits from the integrated shutdown capability for power management.

Part Context

The ADM241LAR belongs to the ADM2xxL family of line drivers and receivers. This family represents an enhanced upgrade to the AD2xx series, offering lower power consumption and faster slew rates. It allows operation with smaller external capacitors compared to previous generations.
