TSS721AD

Drivers, Receivers, Transceivers Overview

The TSS721AD is a half-duplex Meter-Bus transceiver manufactured by Texas Instruments. It integrates one driver and one receiver within a single integrated circuit, designed specifically for M-Bus communication protocols. The device operates on a 3.3V supply voltage and is housed in a 16-SOIC package with dimensions of 0.154 inches (3.90mm) width. It supports surface-mount installation and functions reliably within an operating temperature range of 0°C to 70°C. The component is RoHS3 compliant and classified under the general interface driver and receiver category.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and tape/reel specifications. Ensure the ordering part number matches the required manufacturing revision. Confirm RoHS3 compliance status if environmental regulations apply to the final assembly. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dedicated Meter-Bus transceiver is required for half-duplex communication. Verify that the system power supply aligns with the 3.3V requirement. Ensure the PCB layout accommodates the 16-SOIC footprint. Consider thermal management within the specified 0°C to 70°C operational range for the intended application environment.

Drivers, Receivers, Transceivers Part Context

The TSS721AD belongs to the TSS721 series of Meter-Bus transceivers from Texas Instruments. This series provides specialized interface solutions for utility metering applications. The 'AD' suffix typically denotes the tube packaging variant, distinguishing it from reel-based versions like the ADR. It serves as a core interface element connecting microcontrollers to M-Bus networks.

Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible alternatives within the same family or updated revisions. Verify electrical compatibility regarding voltage levels and protocol support. Consult official substitution guides for any functional equivalents that may have replaced older manufacturing batches.
