74VHC164N

Shift Registers Overview

The Fairchild Semiconductor 74VHC164N is an obsolete 8-bit serial-in parallel-out shift register belonging to the 74VHC series. It features a 14-pin plastic dual in-line package (PDIP) with a 0.300-inch width. The device operates on a supply voltage range of 2V to 5.5V and supports a functional temperature range from -40°C to 85°C. It utilizes push-pull outputs for direct interfacing capabilities.

Shift Registers Feature Summary

• Provides eight-bit serial-to-parallel data conversion functionality
• Features push-pull output drivers for robust signal transmission
• Compatible with standard CMOS, NMOS, and TTL logic families

Shift Registers Applications

• General-purpose serial data processing circuits
• Parallel output expansion in digital systems
• Data storage and buffering applications

Shift Registers Procurement Notes

This component is officially marked as obsolete and no longer manufactured by onsemi. Procurement requires verification of availability through secondary market distributors or authorized surplus channels. Buyers must confirm the authenticity and physical condition of existing stock, as original Fairchild Semiconductor inventory may be limited or discontinued.

Shift Registers Selection Notes

Designers should evaluate active replacements due to the obsolete status of this part. Compatible alternatives include the SN74AHC164N from Texas Instruments or the 74HC164D14 from Diodes Incorporated. Selection criteria should focus on matching the 14-pin DIP footprint, operating voltage range, and logic family compatibility to ensure seamless integration into existing hardware designs.

Shift Registers Part Context

The 74VHC164N is part of the broader 74VHC logic family produced originally by Fairchild Semiconductor, now managed by onsemi. This specific model represents an older generation of high-speed CMOS technology. While functionally similar to other 74HC164 variants, it is distinct within the manufacturer's historical product lineup and is currently excluded from active production schedules.
