DS276S+T&R

Overview

The DS276S+T&R is a low-power RS-232 transceiver in an 8-pin SOIC package. It supports single 3V or 5V logic supply (VCC) and operates within a temperature range of 0°C to +70°C. The device provides full-duplex communication at data rates up to 20 kbps. It features one receiver with single-ended input and one transmitter output. Static supply current is typically 10 µA, while dynamic current reaches 5 mA during active transmission. The component lacks integrated ESD protection.

Feature Summary

• Steals power from the receive signal line to generate negative voltage for the transmitter driver
• Maintains ultra-low static current consumption when the serial port remains idle
• Compatible with standard RS-232-E signal levels for battery-backed systems

Applications

• Battery-powered laptop computers
• Remote sensors
• Portable medical instruments

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel configuration. Confirm that the component meets all required environmental specifications for the intended operating conditions before integration into the design.

Selection Notes

Select this component for applications requiring minimal quiescent current draw on RS-232 ports. Ensure the system design accommodates the unique power stealing mechanism by providing appropriate reservoir capacitance. Verify that the host logic voltage matches the supported 3V or 5V ranges.

Part Context

This part belongs to the DS276 series of line-powered RS-232 transceivers manufactured by Analog Devices / Maxim Integrated. The 'S' designation indicates the 8-pin SOIC package format, while '+T&R' specifies the tape and reel packaging variant for automated assembly processes.
