SN74HCS165DR

Shift Registers Overview

The SN74HCS165DR is an automotive-grade, 8-bit parallel-load shift register from Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports an ambient temperature range of –40°C to +125°C. The device features Schmitt-trigger inputs for noise rejection and balanced CMOS push-pull outputs capable of ±7.8-mA drive current at 6 V. It utilizes a 16-pin SOIC package.

Shift Registers Feature Summary

• Schmitt-trigger inputs provide tolerance for slow or noisy input signals
• Balanced CMOS push-pull outputs support high current drive capabilities
• Low power consumption with minimal static supply current

Shift Registers Applications

• Increasing the number of inputs on a microcontroller
• Parallel-to-serial data conversion in embedded systems
• Cascading multiple registers for expanded I/O expansion

Shift Registers Procurement Notes

Verify the specific ordering suffix 'DR' corresponds to the SOIC-16 package variant. Confirm that the automotive qualification requirements align with the intended application environment. Ensure compatibility with the system's voltage levels and thermal management constraints before finalizing procurement.

Shift Registers Selection Notes

Select this component when robust noise immunity is required due to its Schmitt-trigger architecture. It is suitable for designs needing wide voltage operation between 2 V and 6 V. Consider the SOIC-16 package dimensions for PCB layout constraints compared to other available form factors in the series.

Shift Registers Part Context

This part belongs to the SN74HCS165 family of 8-bit parallel-load shift registers. The 'DR' suffix specifically denotes the SOIC (Small Outline Integrated Circuit) 16-pin package configuration. It shares functional characteristics with other variants like PW, BQB, and DYY, differing primarily in physical footprint and thermal properties.

Shift Registers Replacement Considerations

Direct replacements include SN74HCS165PW, SN74HCS165BQB, and SN74HCS165DYY. Verify pinout compatibility and package dimensions when substituting. Ensure the alternative package meets the same electrical and thermal specifications required by the design.
