74HC164BQ-Q100X

Shift Registers Overview

The Nexperia 74HC164BQ-Q100X is an automotive-grade, 8-bit serial-in/parallel-out shift register. It operates within a supply voltage range of 2.0 V to 6.0 V and features two gated serial data inputs (DSA and DSB) that function as active HIGH enables for data entry. Data shifts on the LOW-to-HIGH clock transitions, while an asynchronous master reset input clears all outputs to LOW. The device utilizes CMOS technology for low power dissipation and high noise immunity.

Shift Registers Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards
• Dual gated serial data inputs allowing flexible data entry control
• Asynchronous master reset capability for immediate output clearing
• DHVQFN package design with side-wettable flanks for automated optical inspection

Shift Registers Applications

• Automotive electronic systems requiring robust logic components
• Serial-to-parallel data conversion circuits
• Parallel output expansion modules
• Digital signal processing interfaces

Shift Registers Procurement Notes

Verify the specific ordering suffix matches the required package variant and temperature grade. Confirm compliance with RoHS directives and REACH regulations prior to integration. Ensure the selected component aligns with the designated automotive application requirements and environmental operating conditions specified in the product documentation.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with dual serial inputs and automotive reliability is required. The DHVQFN package offers space efficiency and thermal performance suitable for compact designs. Verify compatibility with system voltage levels and ensure the asynchronous reset functionality meets the circuit's initialization needs.

Shift Registers Part Context

This part belongs to the 74HC164-Q100 family, which includes variants like the 74HCT164BQ-Q100X. All members share the same core functionality but differ in input logic levels and packaging options. The BQ suffix specifically denotes the DHVQFN14 package type, providing a leadless surface-mount solution optimized for modern PCB layouts.

Shift Registers Replacement Considerations

Direct substitutes include other 74HC164-Q100 variants from Nexperia with different packages or logic families. Cross-manufacturer replacements must match the 8-bit serial-in parallel-out architecture, supply voltage range, and AEC-Q100 qualification status to ensure functional equivalence.
