DS276SN+

Overview

The DS276SN+ is a single RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 20 kb/s. The device features one receiver and one transmitter, utilizing standard RS-232 signaling protocols. It is housed in an SOIC-Narrow-8 package designed for surface mount installation. The operational temperature range spans from 0°C to +70°C. Quiescent current consumption is specified at 100 µA, with active current reaching 5 mA. The component does not include integrated ESD protection circuits.

Feature Summary

• Single-channel RS-232 transceiver functionality
• Low power consumption design
• Standard SOIC-Narrow-8 surface mount packaging

Applications

• Industrial communication equipment requiring serial interfaces
• Portable battery-powered devices needing low current draw
• Embedded systems with RS-232 connectivity requirements

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check for obsolescence notices as the product lifecycle status may indicate limited availability. Ensure package markings match the SOIC-Narrow-8 specification. Validate electrical parameters against the latest datasheet revisions before integration.

Selection Notes

Select this component when a single RS-232 channel is sufficient for the application. Consider the 20 kb/s data rate limit for high-speed requirements. Evaluate the absence of ESD protection if harsh environments are expected. Compare power consumption metrics against alternatives if battery life is critical. Verify thermal performance within the 0°C to +70°C operating range.

Part Context

The DS276SN+ belongs to the Maxim Integrated RS-232 interface family. It serves as a basic transceiver solution for legacy serial communications. The part complements higher-density multi-driver families by offering a minimal pin-count option. Its design focuses on cost-effective integration for simple serial links.

Replacement Considerations

Check for updated versions within the DS276 series. Consult manufacturer cross-reference guides for equivalent single-channel RS-232 transceivers. Verify pin compatibility and electrical specifications before substitution.
