• Computer peripherals including hard drives and CD/DVD ROMs
• Televisions, DVDs, DVRs, and set-top boxes

Shift Registers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type. The D14 designation indicates a PDIP-14 tube package, distinct from SMD options. Confirm RoHS compliance status and lead-free specifications directly with the manufacturer prior to procurement to ensure alignment with project requirements.

Shift Registers Selection Notes

Select this component when an 8-bit serial-to-parallel conversion is required with TTL input compatibility. Ensure the design operates within the specified 4.5V to 5.5V supply voltage range. Consider the PDIP-14 through-hole package constraints during PCB layout if space allows for larger footprints compared to surface-mount alternatives.

Shift Registers Part Context

This part belongs to the 74AHCT164 family of 8-bit parallel-out serial shift registers manufactured by Diodes Incorporated. It utilizes advanced CMOS technology to achieve low power consumption while maintaining high-speed performance suitable for various digital logic applications requiring data storage and transfer functions.

Shift Registers Replacement Considerations

Consult official datasheets for parameter-equivalent substitutes such as the 74HCT164D14 from the same manufacturer. Verify pinout compatibility and electrical characteristics before substituting with parts from other vendors like Texas Instruments.

Shift Registers FAQ

How are the serial data inputs configured?

The serial input data is entered at pins DSA or DSB, which are logically ANDed. Either input can serve as an active HIGH enable with data entry on the other pin.

What is the function of the Master Reset pin?

When asserted LOW, the Master Reset (MR) pin sets all outputs Qn to LOW. This action is asynchronous and overrides all other signals.
