SN74LV165AQWBQBRQ1

Shift Registers Overview

The SN74LV165AQWBQBRQ1 is an automotive-grade, parallel-load, 8-bit shift register designed for operation with a supply voltage (VCC) ranging from 2 V to 5.5 V. It features eight direct data inputs enabled by a low level at the shift/load (SH/LD) pin and provides serial output through QH and complemented serial output Q̅H. The device includes a clock-inhibit function and supports mixed-mode voltage operation on all ports. It is qualified under AEC-Q100 standards for Grade 1 temperature conditions (-40°C to +125°C) and utilizes a wettable flank WQFN-16 package.

Shift Registers Feature Summary

• AEC-Q100 qualified for automotive applications with specified temperature grades and ESD classification levels.
• Supports partial-power-down mode operation via Ioff circuitry that disables outputs to prevent backflow current.
• Features balanced CMOS push-pull outputs capable of sinking and sourcing similar currents.
• Includes wettable flanks in the WBQB package to improve side wetting and facilitate automatic optical inspection.

Shift Registers Applications

• Increasing the number of inputs available to a microcontroller
• Bus interface applications requiring mixed-mode voltage operation
• Input expansion systems utilizing peripheral data loading gates

Shift Registers Procurement Notes

Verify the specific ordering suffix matches the required package type and qualification grade. Confirm that the wettable flank requirement aligns with manufacturing inspection capabilities. Ensure the selected variant meets the specific AEC-Q100 temperature and reliability targets defined for the target automotive application segment.

Shift Registers Selection Notes

Select this component when an 8-bit parallel-to-serial conversion is required within an automotive environment. The wide supply voltage range allows compatibility with various system power rails. Consider the wettable flank package if enhanced solder joint inspectability is necessary for production quality control.

Shift Registers Part Context

This part belongs to the SN74LV165A-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 and automotive qualification status. It serves as a digital logic interface component for expanding input capabilities in vehicle electronics.

Shift Registers Replacement Considerations

Consult the manufacturer's datasheet orderable addendum for alternative packages or variants within the SN74LV165A-Q1 family. Verify pinout and electrical specifications against any potential cross-reference components to ensure functional equivalence in the target design.
