74AHC164D,112

Shift Registers Overview

The Nexperia 74AHC164D,112 is an 8-bit serial-in/parallel-out shift register housed in a SO14 (SOT108-1) plastic small outline package. It features two serial data inputs (DSA and DSB), eight parallel outputs (Q0 to Q7), and a master reset input (MR). Data shifts on LOW-to-HIGH clock transitions. The device operates with a supply voltage range of 2.0 V to 5.5 V. Inputs are overvoltage tolerant up to 5.5 V. Static characteristics include low power dissipation and Schmitt-trigger action on all inputs.

Shift Registers Feature Summary

• Provides serial-to-parallel conversion using dual serial inputs and eight parallel outputs
• Features overvoltage tolerant inputs allowing operation in mixed voltage environments
• Includes Schmitt-trigger action on all inputs for improved noise immunity
• Master reset input actively clears the register to force all outputs LOW

Shift Registers Applications

• Serial-to-parallel data conversion circuits
• Parallel output expansion for microcontrollers
• Digital signal processing interfaces requiring data storage

Shift Registers Selection Notes

Select this component when an 8-bit shift register with parallel outputs is required in a standard SO14 package. Ensure the application voltage falls within the 2.0 V to 5.5 V range. Consider the 74AHCT164 variant if TTL input levels are necessary instead of CMOS levels. Verify thermal requirements against the specified derating curves for the SO14 package.

Shift Registers Part Context

This part belongs to the Nexperia 74AHC/AHCT logic family, utilizing Advanced High-speed CMOS technology. The 'D' designation indicates the SO14 package type. The ',112' suffix denotes specific packaging and marking details defined by Nexperia. This series offers balanced propagation delays and high noise immunity suitable for general-purpose digital logic applications.

Shift Registers Replacement Considerations

The 74AHCT164D,112 serves as a functional equivalent with TTL-compatible input levels. Other package variants such as 74AHC164PW (TSSOP14) or 74AHC164BQ (DHVQFN14) offer alternative form factors with identical electrical functionality.
