TRS208IDWR

Drivers, Receivers, Transceivers Overview

The TRS208IDWR is a low-power RS-232 transceiver manufactured by Texas Instruments, designed for full-duplex data communication. It integrates four drivers and four receivers within a single SOIC-24 package. The device operates at a fixed supply voltage of 5 V with a maximum data rate of 120 kb/s. Key electrical specifications include a typical operating supply current of 20 mA and an electrostatic discharge (ESD) protection rating of 15 kV. The component supports an industrial temperature range from -40°C to +85°C and complies with RoHS standards.

Drivers, Receivers, Transceivers Feature Summary

• Integrates four independent line drivers and four line receivers for multi-channel serial communication
• Provides robust ESD protection rated at 15 kV to safeguard interface connections
• Operates exclusively on a 5 V power supply rail for standard logic compatibility

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring reliable serial data transmission
• Computer peripheral interfaces utilizing RS-232 protocols
• Embedded devices needing compact full-duplex communication channels

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix IDWR confirms the SOIC-24 surface-mount package and tape-and-reel shipping format. Confirm that the 5 V supply requirement aligns with the target system design. Ensure compliance with RoHS directives is required for the intended market. Check for any recent product change notifications regarding manufacturing sites or material composition updates before finalizing orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when four independent RS-232 channels are necessary within a limited board area. The fixed 5 V operation distinguishes it from dual-voltage alternatives like the MAX3232. The SOIC-24 package offers a balance between pin count and footprint size compared to wider SSOP variants. Consider the 20 mA quiescent current if power efficiency during active states is a primary constraint.

Drivers, Receivers, Transceivers Part Context

This part belongs to the TRS208 series, which serves as a functional equivalent to the legacy MAX208 family. It provides a direct pin-compatible upgrade path for designs originally using older generation RS-232 transceivers. The IDWR designation specifically denotes the industrial temperature grade and the reel packaging format used for automated assembly processes.

Drivers, Receivers, Transceivers Replacement Considerations

The TRS208IDBR is a compatible alternative featuring identical electrical characteristics but housed in a 24-SSOP package. Designers must verify that the PCB footprint accommodates the different package width and pin pitch between SOIC and SSOP formats before substituting.
