DS275SN+

Overview

The DS275SN+ is a line-powered RS-232 transceiver integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5V to 5.5V and supports full-duplex communication with one receiver and one driver. The device utilizes an 8-SOIC surface-mount package with a width of 3.90mm. It functions reliably across an operating temperature range of 0°C to 70°C. The component features a receiver hysteresis of 800 mV and draws power from the RS-232 signal lines, eliminating the need for a separate negative supply voltage.

Feature Summary

• Line-powered operation eliminates the requirement for external negative voltage supplies
• Full-duplex RS-232 data transmission capability
• Integrated receiver hysteresis for noise immunity

Applications

• Industrial serial communication interfaces
• Embedded systems requiring RS-232 connectivity
• Equipment with limited power supply options

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check for obsolescence notices since this part may be discontinued. Ensure packaging matches specifications for handling and storage requirements.

Selection Notes

Select this component when a single-channel RS-232 transceiver is required without negative supply generation. Consider the 8-SOIC package dimensions for PCB layout constraints. Verify that the 0°C to 70°C operating temperature range meets environmental conditions. Compare against alternatives if ESD protection or higher data rates are necessary.

Part Context

This component belongs to the Maxim Integrated RS-232 interface family, designed for low-power serial communication applications. It serves as a complete solution for converting TTL/CMOS logic levels to RS-232 voltages. The product line emphasizes simplicity and reliability for standard serial port implementations.

Replacement Considerations

Check for equivalent parts such as the DS275S+ variant. Verify pin compatibility and electrical specifications before substitution. Confirm package integrity and thermal characteristics match the original design requirements.
