SN65HVS881PWPR

Overview

The SN65HVS881PWPR is an industrial-grade serializer manufactured by Texas Instruments, designed to convert parallel digital inputs into a single serial output stream. It supports eight digital input channels with a data rate of 1 Mb/s. The device operates on a wide supply voltage range from 10 V to 34 V and functions within a temperature range of -40°C to +125°C. Housed in a 28-pin HTSSOP package, it features SMD/SMT mounting. Key specifications include a maximum power supply voltage of 34 V and a minimum of 10 V. The component is moisture sensitive and belongs to the SN65HVS881 series.

Feature Summary

• Converts eight parallel digital input channels into a single high-speed serial output stream for efficient signal transmission.
• Includes integrated diagnostic capabilities to monitor device health and detect faults such as open or shorted inputs.
• Engineered for industrial environments with extended operating temperature ranges and wide power supply voltage tolerance.

Applications

• Industrial automation systems requiring reliable digital input serialization
• Factory automation controllers and PLCs
• Process control networks with harsh environmental conditions

Procurement Notes

Verify the exact suffix against the manufacturer's current documentation, as packaging options may vary between tube and reel configurations. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability fluctuates. Ensure storage conditions account for moisture sensitivity levels prior to soldering to prevent damage during assembly processes.

Selection Notes

Select this component when eight parallel digital inputs must be serialized over a single differential pair. Compare with the SN65HVS882 if diagnostics are not required, or the SN65HVS883 for different packaging needs. Ensure the system voltage aligns with the 10 V to 34 V operating range. Verify thermal management requirements for the HTSSOP-28 package under maximum load conditions.

Part Context

This part belongs to the SN65HVS88x family of industrial serializers from Texas Instruments. It shares core architecture with the SN65HVS882 but adds diagnostic features. The PWPR suffix indicates a tape-and-reel packaging format suitable for automated surface-mount assembly, distinguishing it from the tube-packaged PWP variant.

Replacement Considerations

The SN65HVS882PWP serves as a functional alternative lacking diagnostic features. The SN65HVS883PWPR offers similar serialization but may differ in packaging or temperature ratings. Verify pin compatibility and software configuration before substitution.
