SN65HVS882PWP

Overview

The SN65HVS882PWP is an eight-channel digital input serializer manufactured by Texas Instruments. It converts parallel inputs into a serial output stream at a data rate of 1 Mb/s. The device operates within a supply voltage range of 10 V to 34 V and supports industrial temperature conditions from -40°C to +125°C. It features eight parallel inputs and one serial output, housed in a 28-pin HTSSOP package designed for surface mount technology.

Feature Summary

• Accepts wide-range digital input voltages directly from industrial sensors without external level shifting
• Integrates diagnostic capabilities including open-load detection and short-to-ground protection
• Supports cascading configurations to increase channel density via SPI interface

Applications

• Industrial automation systems requiring robust digital input expansion
• Motor drive units needing reliable sensor signal acquisition
• Programmable logic controllers (PLCs) with high noise immunity requirements

Procurement Notes

Verify the specific suffix PWP confirms the HTSSOP-28 tube packaging format. Confirm RoHS compliance status through official documentation as manufacturing processes may evolve. Check for End-of-Life notices or obsolescence warnings prior to finalizing procurement plans to ensure long-term supply stability.

Selection Notes

Select this component when interfacing 24V industrial signals with low-voltage microcontrollers. Ensure the design accommodates the 10V minimum operating voltage. Verify that the SPI communication protocol matches the host controller's capabilities. Consider thermal management for operation near the upper temperature limit.

Part Context

This part belongs to the SN65HVS88x family of high-voltage serializers. It shares functional similarities with the SN65HVS881 but offers specific pinout or feature variations defined by the manufacturer. It serves as a bridge between harsh industrial environments and sensitive control electronics.

Replacement Considerations

The SN65HVS881PWPR is a related variant within the same family. Verify pin compatibility and software register mapping before substitution. Review datasheet differences regarding diagnostic features and power consumption characteristics.
