SN74HCS165QBQBRQ1

Shift Registers Overview

The SN74HCS165QBQBRQ1 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 ambient temperatures from -40°C to +125°C. The device features Schmitt-trigger inputs for noise tolerance and balanced CMOS push-pull outputs capable of ±7.8 mA drive current at 6 V. It utilizes a 16-pin WQFN (WBQB) package with wettable flanks.

Shift Registers Feature Summary

• AEC-Q100 qualified for automotive applications
• Schmitt-trigger inputs support slow or noisy signals
• Balanced CMOS push-pull outputs provide high drive capability
• Wettable flank QFN package enables automatic optical inspection

Shift Registers Applications

• Increase the number of inputs on a microcontroller
• Cascaded data acquisition systems
• Peripheral interface expansion in automotive electronics

Shift Registers Procurement Notes

Verify that the specific ordering suffix matches the required WBQB package variant. Confirm AEC-Q100 qualification requirements align with the target automotive application grade. Ensure design specifications accommodate the specified operating temperature range and voltage limits.

Shift Registers Selection Notes

Select this component when system requirements demand wide voltage operation between 2 V and 6 V. The inclusion of Schmitt-trigger inputs makes it suitable for environments with significant signal noise or slow transition times. The wettable flank package facilitates reliable automated assembly and inspection processes.

Shift Registers Part Context

This part belongs to the SN74HCS165-Q1 family of automotive parallel-load shift registers. It shares functional characteristics with other members of the series but is distinguished by its specific WBQB packaging configuration. The family provides scalable solutions for expanding digital input capabilities in vehicle control units.

Shift Registers Replacement Considerations

Direct substitutes include other SN74HCS165-Q1 variants such as SN74HCS165PW-Q1, SN74HCS165D-Q1, SN74HCS165BQB-Q1, and SN74HCS165DYY-Q1, provided the package footprint and thermal requirements are compatible.
