74AHC164D-Q100J

Shift Registers Overview

The Nexperia 74AHC164D-Q100J is an 8-bit serial-in/parallel-out shift register qualified to AEC-Q100 Grade 1 for automotive use. It features two serial data inputs (DSA, DSB) and eight parallel outputs (Q0–Q7). Data shifts on LOW-to-HIGH clock transitions, with a master reset forcing all outputs LOW. The device operates from 2.0 V to 5.5 V, supporting CMOS input levels. It is housed in a SO14 package (SOT108-1) and functions within temperature ranges of -40 °C to +85 °C and -40 °C to +125 °C.

Shift Registers Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Overvoltage tolerant inputs enabling translation in mixed voltage environments
• Schmitt-trigger action on all inputs for improved noise immunity
• High ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)

Shift Registers Applications

• Automotive electronic systems requiring grade 1 component qualification
• Mixed voltage signal translation between different logic families
• Serial-to-parallel data conversion circuits
• Digital control interfaces utilizing shift register functionality

Shift Registers Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the AEC-Q100 Grade 1 qualification aligns with project automotive reliability requirements. Ensure supply voltage and temperature range specifications meet system operating conditions. Check pinout compatibility with existing PCB footprints before integration.

Shift Registers Selection Notes

Select this component when automotive-grade reliability is mandatory. Choose over standard logic if mixed-voltage interfacing is required due to overvoltage tolerant inputs. Consider the SO14 package dimensions for board space constraints. Verify input level compatibility, as this variant supports CMOS levels unlike the AHCT counterpart which requires TTL levels.

Shift Registers Part Context

This part belongs to the Nexperia 74AHC/AHCT164-Q100 family of 8-bit shift registers. The 'D' suffix indicates the SO14 plastic small outline package. The 'Q100' designation confirms automotive qualification. It shares functional architecture with non-automotive variants but includes enhanced testing and reliability documentation specific to automotive applications.

Shift Registers Replacement Considerations

Direct substitutes include other 74AHC164 variants in SO14 packages from compatible manufacturers, provided they meet AEC-Q100 Grade 1 requirements. Non-automotive 74AHC164 devices may function electrically but lack the specified automotive qualification. Verify pinout and electrical characteristics match exactly before substitution.
