SN74HC164PWRE4

Shift Registers Overview

The SN74HC164PWRE4 is an 8-bit parallel-out serial shift register from the Texas Instruments SN74HC164 family. It operates within a supply voltage range of 2 V to 6 V and features AND-gated serial inputs (A and B) alongside an asynchronous clear (CLR) input. The device utilizes a TSSOP-14 package with a nominal body size of 5.00 mm × 4.40 mm. It supports clock frequencies up to 36 MHz at 6 V and provides push-pull outputs capable of driving up to 10 LSTTL loads.

Shift Registers Feature Summary

• AND-gated serial inputs for complete control over incoming data entry
• Asynchronous direct clear function to reset all registers immediately
• Fully buffered clock and serial inputs for signal integrity

Shift Registers Applications

• Programmable Logic Controllers
• Appliances
• Video Display Systems
• Output Expander

Shift Registers Procurement Notes

Verify that the ordering suffix 'E4' corresponds to lead-free manufacturing processes as specified in the manufacturer's documentation. Confirm the specific package variant matches the required PCB footprint, as the PW designation indicates a TSSOP-14 housing. Ensure compliance with RoHS directives and check for any military-grade testing requirements if applicable to the project specifications.

Shift Registers Selection Notes

Select this component when an 8-bit serial-to-parallel conversion is required with low power consumption. The HC logic family offers wide voltage compatibility suitable for various digital systems. Consider the asynchronous clear feature for immediate system resets and the gated inputs for precise data synchronization without additional external gating components.

Shift Registers Part Context

This part belongs to the SNx4HC164 series of 8-bit shift registers manufactured by Texas Instruments. The series includes variants such as SN74HC164D and SN74HC164N, differing primarily in packaging styles like SOIC or PDIP. The PWRE4 suffix specifically denotes the TSSOP package with reel-based carrier configuration.
