TRS3221ECDBR

Drivers, Receivers, Transceivers Overview

The TRS3221ECDBR is a single-channel RS-232 transceiver manufactured by Texas Instruments, housed in an SSOP-16 package. It supports data rates up to 1 Mb/s and operates on a full-duplex basis. The device functions within a supply voltage range of 3 V to 5.5 V, with typical operation at 3.3 V or 5 V. It features low quiescent current of 1 mA and includes a shutdown mode for power conservation. ESD protection is rated at 15 kV, ensuring robust performance in industrial environments. The component operates between 0°C and +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Single-channel RS-232 transceiver supporting full-duplex communication
• Integrated shutdown mode for reduced power consumption
• High electrostatic discharge (ESD) protection capability
• Low operating current suitable for battery-powered applications

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring serial communication
• Portable equipment needing low-power RS-232 interfaces
• Embedded systems with limited power budgets

Drivers, Receivers, Transceivers Procurement Notes

Verify the exact suffix 'CDBR' against official Texas Instruments documentation to confirm the SSOP-16 package and commercial temperature grade. Ensure compatibility with existing PCB footprints for SSOP-16 components. Cross-reference datasheet revisions to confirm pinout consistency with legacy designs. Confirm RoHS compliance status through manufacturer declarations prior to integration into regulated products.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-channel RS-232 interface is required with moderate speed up to 1 Mb/s. It is appropriate for designs operating between 3 V and 5.5 V where low standby current is critical. Compare against the TRSF3221E series if extended temperature ranges or different packaging options are needed. Verify that the SSOP-16 footprint matches the target board layout constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments TRS3221E family of RS-232 transceivers. It shares functional similarities with the TRSF3221E series but may differ in specific electrical characteristics or packaging options. The TRS3221ECDBR specifically denotes the SSOP-16 variant designed for surface-mount assembly. It serves as a direct replacement for older single-channel RS-232 drivers in modern low-voltage systems.

Drivers, Receivers, Transceivers Replacement Considerations

The TRSF3221ECDBR is a related variant within the same product family, offering similar functionality but potentially differing in temperature range or package type. Direct substitution requires verifying pinout compatibility and electrical parameter alignment with the original design specifications.
