74VHC164SJ

Shift Registers Overview

The Fairchild Semiconductor 74VHC164SJ is an obsolete 8-bit serial-in, parallel-out shift register belonging to the VHC/VHCT CMOS logic family. It operates on a supply voltage range of 2V to 5.5V and supports surface-mount packaging in a 14-SOIC case with a width of 5.30mm. The device features push-pull outputs and functions as a unidirectional serial-to-parallel converter. Operating temperature specifications extend from -40°C to +85°C, with a turn-on delay time of 18.5ns.

Shift Registers Feature Summary

• Provides 8-bit serial input to parallel output conversion capability
• Utilizes VHC/VHCT CMOS technology for low power consumption
• Features push-pull output drivers for robust signal integrity

Shift Registers Applications

• Serial-to-parallel data conversion in digital systems
• General-purpose shift register applications requiring 8-bit storage
• Interface circuits connecting serial communication lines to parallel buses

Shift Registers Procurement Notes

This component is officially discontinued and marked as obsolete by Fairchild Semiconductor. Verification of availability should focus on secondary market distributors or surplus suppliers rather than direct manufacturer channels. Confirm RoHS compliance status carefully, as sources indicate potential non-compliance for specific batches. Ensure the package matches the 14-SOIC specification before procurement.

Shift Registers Selection Notes

Select this part only if legacy compatibility with the 74VHC series is required. Note that it lacks bidirectional counting capabilities found in counter ICs like the 74F193. Verify that the 2V to 5.5V operating range meets system requirements. Consider modern equivalents if new designs are being developed, as production has ceased.

Shift Registers Part Context

The 74VHC164SJ is part of the broader 74VHC logic family, designed for high-speed CMOS applications. Unlike binary counters such as the 74F193, which handle up/down counting, this device focuses strictly on data shifting. It was manufactured by Fairchild Semiconductor, now part of onsemi, and serves as a standard solution for basic serial data expansion tasks.

Shift Registers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the part is obsolete, users must identify cross-references through distributor databases or consult current onsemi product portfolios for compatible 8-bit shift registers.
