SN74LV8T164BQAR

Shift Registers Overview

The SN74LV8T164BQAR is an automotive-grade, 8-bit parallel-load shift register from Texas Instruments. It operates on a single power supply ranging from 1.65V to 5.5V and supports mixed-mode voltage operation for interfacing with diverse system components. The device features latching logic with a known power-up state to ensure consistent start-up behavior. It is housed in a 14-pin WQFN package with an exposed pad, designed for surface-mount applications in harsh environments.

Shift Registers Feature Summary

• Supports mixed-mode voltage operation for flexible system integration
• Provides latching logic with a defined power-up state for reliable initialization
• Automotive qualification ensures durability in demanding operating conditions

Shift Registers Applications

• Automotive electronic control units requiring serial-to-parallel conversion
• Industrial systems needing robust data shifting under variable voltage
• Embedded controllers utilizing mixed-voltage logic interfaces

Shift Registers Procurement Notes

Verify the specific suffix 'BQAR' matches your design requirements, as it denotes the automotive grade, WQFN package, and tape-and-reel packaging configuration. Confirm that the 1.65V to 5.5V supply range aligns with your target circuit's voltage levels. Ensure thermal management considerations are addressed due to the exposed pad design in the WQFN-14 package. Cross-reference the datasheet revision date to guarantee compatibility with current manufacturing standards.

Shift Registers Selection Notes

Select this component when automotive reliability and mixed-voltage compatibility are critical. It is suitable for designs requiring a defined power-up state to prevent undefined logic states during startup. Consider the WQFN-14 package if space constraints exist alongside the need for thermal dissipation through the exposed pad. Ensure the input signals are compatible with the LV logic family thresholds across the specified temperature range.

Shift Registers Part Context

This part belongs to the SN74LV8T164 family of 8-bit parallel-load shift registers. It shares functional similarities with non-automotive variants but includes enhanced specifications for automotive use. The device complements other LV series logic components by providing serial-to-parallel data conversion capabilities within a compact surface-mount footprint.

Shift Registers Replacement Considerations

Direct substitutes include other automotive-qualified 8-bit shift registers from the same manufacturer family. Verify pinout compatibility and electrical characteristics before swapping. Non-automotive equivalents may lack the required temperature range or reliability certifications.
