74VHC164SJX

Shift Registers Overview

The Fairchild Semiconductor 74VHC164SJX is an 8-bit serial-in, parallel-out shift register belonging to the VHC logic family. It operates within a supply voltage range of 2V to 5.5V and supports an operating temperature range of -40°C to 85°C. The device converts serial data into parallel outputs using a push-pull output configuration. It is housed in a TSSOP-20 package with 20 pins.

Shift Registers Feature Summary

• Performs serial-to-parallel data conversion for digital signal processing
• Operates across a wide voltage range from 2V to 5.5V
• Features push-pull outputs for robust signal driving

Shift Registers Applications

• Data storage and buffering in digital systems
• Serial communication interface expansion
• Parallel output generation from serial data streams

Shift Registers Procurement Notes

Verify component authenticity as this part is obsolete and no longer manufactured by Fairchild or onsemi. Confirm RoHS compliance status, as some listings indicate non-compliance. Check for valid substitutes like Nexperia 74AHC164D,118 if availability is required. Ensure the supplier provides original datasheets for technical validation before procurement.

Shift Registers Selection Notes

Select this component only if legacy compatibility with Fairchild pinouts and electrical characteristics is strictly required. Consider modern equivalents such as the 74AHC164 series for improved availability and potentially enhanced performance metrics. Verify that the TSSOP-20 package fits the target PCB layout constraints and thermal requirements.

Shift Registers Part Context

This component is part of the 74VHC logic family, designed for high-speed CMOS applications. It shares functional similarities with other 8-bit shift registers but is distinguished by its specific voltage and speed characteristics defined by the VHC standard. The SJX suffix typically denotes the TSSOP-20 packaging variant.

Shift Registers Replacement Considerations

The 74AHC164D,118 by Nexperia USA Inc. is listed as a similar available substitute. Verify pinout compatibility and electrical parameter alignment before substitution.
