DS275E/T&R

Overview

The DS275E/T&R is a line-powered RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features one driver and one receiver, supporting full-duplex communication over the RS-232 protocol. The device operates within a voltage range of 4.5V to 5.5V and functions at temperatures between 0°C and +70°C. It utilizes an 800 mV receiver hysteresis for signal integrity. Available in surface-mount packages including 14-TSSOP and 8-SOIC, it is currently classified as obsolete.

Feature Summary

• Line-powered operation eliminates external power requirements for the transceiver circuit
• Full-duplex data transmission capability via integrated single driver and receiver
• RS-232 protocol compliance with defined receiver hysteresis characteristics

Applications

• Industrial serial communication interfaces
• Embedded system data link connections
• Legacy equipment interface adaptation

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted to remaining stock or third-party distributors. Verify authenticity through authorized channels due to potential counterfeit risks associated with discontinued parts. Confirm package variant compatibility before acquisition.

Selection Notes

Designers should evaluate alternative active components for new projects given the obsolete status. Ensure the selected replacement supports identical pinout configurations if board space is constrained. Verify that the substitute meets the required 4.5V to 5.5V operating voltage and temperature range specifications.
