74AHCT164D-Q100J

Shift Registers Overview

The 74AHCT164D-Q100J is an 8-bit serial-in/parallel-out shift register from the Nexperia 74AHCT164-Q100 family. It features two serial data inputs (DSA, DSB) and eight parallel outputs (Q0–Q7). Data shifts on LOW-to-HIGH clock transitions. The device operates with a supply voltage range of 4.5 V to 5.5 V. Propagation delay is typically 3.4 ns at 15 pF load. Input levels are TTL compatible. It is qualified to AEC-Q100 Grade 1 for automotive use.

Shift Registers Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards
• TTL input levels for compatibility with standard logic families
• Overvoltage tolerant inputs allowing operation in mixed voltage environments
• Schmitt-trigger action on all inputs for noise immunity

Shift Registers Applications

• Automotive electronic systems requiring serial-to-parallel conversion
• Mixed voltage interface circuits utilizing overvoltage tolerance
• Industrial control applications operating within specified temperature ranges

Shift Registers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Ensure the component meets AEC-Q100 Grade 1 requirements for the intended automotive application. Cross-reference the datasheet revision date to confirm the validity of electrical characteristics before finalizing design integration.

Shift Registers Selection Notes

Select this component when TTL-compatible inputs are required alongside high-speed serial shifting capabilities. The DHVQFN package option supports automatic optical inspection via side-wettable flanks. Consider the wide operating temperature range and robust latch-up performance for harsh environment deployment.

Shift Registers Part Context

This part belongs to the 74AHC/AHCT164-Q100 series of 8-bit shift registers. The 'AHCT' designation indicates TTL-compatible input thresholds, distinguishing it from the HC variant which uses CMOS levels. The '-Q100' suffix denotes automotive qualification. The 'D' suffix specifies the SO14 plastic small outline package.

Shift Registers Replacement Considerations

Direct substitutes include other 74AHCT164 variants from Nexperia such as the 74AHCT164PW-Q100 or 74AHCT164BQ-Q100, provided the package footprint matches the design constraints.
