74HC164D-Q100J

Shift Registers Overview

The Nexperia 74HC164D-Q100J is an automotive-grade, 8-bit serial-in, parallel-out shift register. It features two gated serial data inputs (DSA and DSB) and eight parallel outputs (Q0 to Q7). Data shifts on LOW-to-HIGH clock transitions. An active LOW master reset clears the register. The device operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. It complies with AEC-Q100 Grade 1 standards and JEDEC JESD7A specifications.

Shift Registers Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 for extended temperature reliability
• Gated serial data inputs allowing either input to function as an enable control for the other
• Asynchronous master reset that forces all outputs LOW independently of clock or data signals
• Input clamp diodes enabling interface to voltages exceeding VCC using current limiting resistors

Shift Registers Applications

• Automotive electronic systems requiring robust logic shifting
• Serial-to-parallel data conversion interfaces
• Parallel output expansion for microcontroller systems
• Industrial control applications operating under wide temperature conditions

Shift Registers Procurement Notes

Verify the specific ordering suffix 'J' against the manufacturer's latest documentation to confirm package type and tape/reel specifications. Confirm the exact temperature grade (-40 °C to +125 °C) matches the design requirements. Ensure compatibility with the SO14 plastic small outline package dimensions before finalizing procurement orders.

Shift Registers Selection Notes

Select this component when an 8-bit serial-to-parallel converter is required for automotive environments. The HC logic family provides CMOS low power dissipation and high noise immunity suitable for noisy vehicle networks. Verify that the 2.0 V to 6.0 V supply range aligns with the system power architecture and that the SO14 package fits the PCB layout constraints.

Shift Registers Part Context

This part belongs to the Nexperia 74HC164-Q100 series, which includes variants like the 74HCT164D-Q100J. The series offers multiple package options including SO14, TSSOP14, and DHVQFN14. All variants share the same functional description but differ in physical footprint and thermal characteristics while maintaining AEC-Q100 Grade 1 qualification.

Shift Registers Replacement Considerations

The 74HCT164D-Q100J serves as a compatible alternative if TTL-level input compatibility is required instead of CMOS levels. Other package variants such as 74HC164PW-Q100 or 74HC164BQ-Q100 provide equivalent functionality in different form factors.
