AD241JR

Overview

The AD241JR is a five-volt powered CMOS RS-232 transceiver manufactured by Analog Devices Inc. It integrates four drivers and five receivers to support full-duplex communication on the RS-232 serial interface standard. The device operates with a single +5V power supply, eliminating the need for external charge pumps or negative voltage rails typically required by earlier RS-232 standards. Designed for surface-mount installation, it provides robust signal transmission for data communication applications requiring reliable serial connectivity.

Feature Summary

• Integrates four independent drivers and five independent receivers in a single package
• Operates from a single +5V power supply without external charge pump requirements
• Supports full-duplex data transmission compliant with RS-232 interface specifications
• Features shutdown capability to minimize power consumption during idle periods

Applications

• Industrial equipment serial communication ports
• Computer peripheral interfacing and modem connections
• Point-of-sale systems and barcode scanners
• Test and measurement instrument control interfaces

Procurement Notes

Verify the specific suffix 'JR' against the manufacturer's official datasheet to confirm package type and temperature range. Ensure compatibility with system voltage levels and interface protocols before integration. Check for current availability status as component lifecycles may change. Confirm RoHS compliance requirements match project specifications.

Selection Notes

Select this component when a compact, single-supply RS-232 solution is required for full-duplex communication. Consider the pin count and package constraints relative to available board space. Evaluate the drive strength and receiver sensitivity against cable length and noise environment requirements. Compare performance metrics with alternative transceivers if lower power or higher data rates are necessary.

Part Context

This part belongs to the MAX241 family of RS-232 transceivers, which are widely used for serial communication. The family is known for providing complete RS-232 functions with minimal external components. These devices are commonly found in embedded systems and industrial controls where reliable serial data transfer is critical. The AD241 variant maintains the core functionality while offering specific packaging options for different manufacturing needs.
