TRS211IDWG4

Drivers, Receivers, Transceivers Overview

The TRS211IDWG4 is a Texas Instruments multichannel RS-232 line driver and receiver designed for single 5-V supply operation. It integrates four drivers and five receivers with dual charge pumps requiring only four 0.1-μF external capacitors. The device supports data rates up to 120 kbit/s with a maximum slew rate of 30 V/μs. Bus-pin ESD protection exceeds ±15 kV using the Human-Body Model. It features shutdown (SHDN) and enable (EN) control pins, reducing typical supply current to 1 μA in shutdown mode. Operating temperature range is -40°C to +85°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the latest TI Package Option Addendum to confirm package type and availability status. Ensure the component meets RoHS and environmental compliance requirements for the target application. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring multiple independent RS-232 channels within a single package. The integrated charge pump eliminates the need for negative voltage supplies, simplifying board layout. Verify that the required data rate does not exceed 120 kbit/s and that the operating environment falls within the specified industrial temperature range.

Drivers, Receivers, Transceivers Part Context

This part belongs to the TRS211 family of 5-V multichannel RS-232 transceivers. The IDWG4 designation indicates an industrial temperature range (-40°C to +85°C), SOIC-Wide (DW) package, and lead-free/green construction. It serves as a direct interface between TTL/CMOS logic and RS-232 serial connectors.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible alternatives include the TRS211CDW variants for commercial temperature ranges or other multichannel RS-232 devices from the same manufacturer family. Verify electrical characteristics match if substituting with components from different manufacturers.
