74AHC164BQ-Q100X

Shift Registers Overview

The Nexperia 74AHC164BQ-Q100X is an automotive-grade, 8-bit serial-in/parallel-out shift register. It features two serial data inputs (DSA and DSB) and eight parallel outputs (Q0 to Q7). Data shifts on the LOW-to-HIGH clock transition, while a LOW master reset clears all outputs. The device operates with a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. Inputs are overvoltage tolerant up to 5.5 V. Propagation delay ranges from 1.0 ns to 16.0 ns depending on load capacitance and voltage.

Shift Registers Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards for reliability in vehicle applications.
• Overvoltage tolerant inputs allow safe interfacing in mixed-voltage environments without external protection.
• Schmitt-trigger actions on all inputs ensure high noise immunity and jitter-free output signals.
• DHVQFN package includes side-wettable flanks to enable automatic optical inspection of solder joints.

Shift Registers Applications

• Automotive electronic systems requiring robust logic shifting capabilities.
• Mixed-voltage signal translation between different logic domains.
• Data storage and transfer in serial-to-parallel conversion circuits.

Shift Registers Procurement Notes

Verify that the specific ordering suffix matches the required package variant and temperature grade. Confirm that the component meets the AEC-Q100 Grade 1 qualification requirements for your target application. Ensure input voltage levels remain within the specified tolerance limits to prevent damage. Check the latest datasheet revision for any updates to pin configurations or electrical characteristics before finalizing design integration.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with automotive reliability is required. The wide supply voltage range accommodates various system power rails. Overvoltage tolerant inputs simplify interface design in multi-voltage architectures. The DHVQFN package offers a compact footprint suitable for space-constrained printed circuit board layouts.

Shift Registers Part Context

This part belongs to the Nexperia 74AHC/AHCT164-Q100 family of 8-bit shift registers. It shares functional compatibility with other variants in the series but differs in package type and specific electrical parameters based on the logic family. The BQ suffix denotes the DHVQFN14 package configuration.

Shift Registers Replacement Considerations

Verify pinout compatibility and electrical specifications against alternative shift registers. Ensure substitute components meet the same AEC-Q100 Grade 1 qualification if automotive use is intended. Check for equivalent overvoltage tolerance and operating temperature ranges to maintain system reliability.
