CD4021BQDRQ1

Shift Registers Overview

The CD4021BQDRQ1 is an automotive-grade AC CMOS octal 3-state register manufactured by Texas Instruments. It features a serial-to-serial/parallel counting sequence and operates within a temperature range of -40°C to +125°C. The device is housed in a SOIC-16 package and meets AEC-Q100 qualification standards for automotive applications.

Shift Registers Feature Summary

• Automotive grade reliability with AEC-Q100 certification
• AC CMOS technology for low power consumption
• Octal 3-state register architecture
• Wide operating temperature range

Shift Registers Applications

• Automotive data acquisition systems
• Industrial control interfaces
• Automotive sensor input registration

Shift Registers Procurement Notes

Verify the specific suffix QDRQ1 against the official datasheet to confirm the SOIC-16 package and automotive qualification status. Ensure the component matches the required AEC-Q100 grade for your target application environment. Confirm RoHS compliance details directly from the manufacturer's documentation before finalizing procurement specifications.

Shift Registers Selection Notes

Select this component when an automotive-certified, low-power octal shift register is required. The AC CMOS process offers advantages in power efficiency compared to standard logic families. Verify that the SOIC-16 package dimensions fit the PCB layout constraints and that the -40°C to +125°C operating range covers the environmental conditions of the intended system.

Shift Registers Part Context

This part belongs to the CD4021B series of octal 3-state registers. The 'Q' suffix indicates automotive qualification, while 'D' denotes the SOIC package and 'RQ1' specifies the reel packaging and automotive grade. It is designed for robust performance in demanding automotive environments requiring reliable data shifting and storage capabilities.

Shift Registers Replacement Considerations

Check for direct equivalents within the CD4021B family or other automotive-grade octal shift registers from Texas Instruments. Ensure any substitute maintains the same AEC-Q100 qualification, SOIC-16 footprint, and AC CMOS electrical characteristics to guarantee compatibility.
