SN74LVC165ABQBR

Shift Registers Overview

The SN74LVC165ABQBR is an automotive-grade, 8-bit parallel-load shift register manufactured by Texas Instruments. It operates within a supply voltage range of 1.1 V to 3.6 V and features push-pull outputs with high drive capability. The device utilizes a WQFN-16 package and supports serial-to-parallel data conversion. It includes asynchronous parallel input loading and a clock inhibit function for precise timing control. Designed for harsh environments, it meets AEC-Q100 standards and functions reliably across temperatures from -40°C to +125°C.

Shift Registers Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle applications
• Asynchronous parallel load capability allows immediate data capture independent of the clock signal
• Clock inhibit feature enables precise synchronization and prevents unintended shifting during operation

Shift Registers Applications

• Automotive sensor interface modules requiring robust digital input expansion
• Vehicle body control units managing multiple switch inputs
• Infotainment system peripheral data acquisition circuits

Shift Registers Procurement Notes

Verify the specific suffix 'BQBR' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets the required AEC-Q100 grade for your target automotive application. Cross-reference the ordering information with official Texas Instruments documentation to avoid discrepancies in pinout or electrical characteristics.

Shift Registers Selection Notes

Select this component when designing systems that require low-voltage operation down to 1.1 V combined with automotive reliability standards. The LVC technology offers fast switching speeds suitable for high-frequency data transmission. Consider the WQFN-16 footprint for compact board layouts where space constraints are critical compared to traditional packages.

Shift Registers Part Context

This part belongs to the SN74LVC165A family of 8-bit shift registers. It shares functional similarities with other members like the SN74LVC165AWBQBRQ1 but may differ in packaging or specific automotive qualification details. The LVC series is characterized by its wide operating voltage range and compatibility with various logic families, making it versatile for mixed-voltage designs.

Shift Registers Replacement Considerations

Check for direct equivalents such as the SN74LVC165AWBQBRQ1 if pin compatibility and package dimensions match exactly. Verify that any substitute maintains the same AEC-Q100 certification level and electrical parameters to ensure seamless integration without redesigning the circuit.
