ADM241LJRZ-REEL

Overview

The ADM241LJRZ-REEL is a CMOS RS-232 transceiver designed for single 5 V power supply operation. It integrates four drivers and five receivers, featuring internal charge pumps that generate ±10 V supplies from the 5 V input using only four 1 µF capacitors. The device supports data rates up to 120 kbps and includes low power shutdown and enable functions. It operates within an industrial temperature range of -40°C to +85°C and is housed in a 28-pin SOIC package.

Feature Summary

• Integrates four drivers and five receivers with on-board DC-to-DC converters
• Features low power shutdown mode reducing dissipation below 5 µW
• Includes receiver enable function for microprocessor bus sharing
• Operates from a single 5 V supply without requiring external voltage sources

Applications

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

Procurement Notes

Verify the J suffix indicates the commercial temperature grade (0°C to 70°C) or confirm if the datasheet specifies industrial (-40°C to +85°C) for this specific suffix variant. Ensure the REEL suffix matches the required tape and reel packaging format for automated assembly processes.

Selection Notes

Select the ADM241L when five receiver channels are required alongside four drivers. Verify compatibility with EIA-232-E specifications regarding output swing and input thresholds. Confirm that the 1 µF capacitor requirement fits the board space constraints compared to older generations requiring larger values.

Part Context

This component belongs to the ADM2xxL family of line drivers and receivers. It serves as an enhanced upgrade to the AD2xx series, offering lower power consumption and faster slew rates. The ADM241L specifically provides the highest channel count within the standard 5 V single-supply group.

Replacement Considerations

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