SN74HC164DRG3

Shift Registers Overview

The SN74HC164DRG3 is an 8-bit parallel-out serial shift register from the Texas Instruments SNx4HC164 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 14-pin SOIC package with a nominal body size of 8.65 mm by 3.91 mm. It provides push-pull outputs capable of driving up to 10 LSTTL loads, with typical propagation delays ranging from 20 ns to 35 ns depending on voltage conditions.

Shift Registers Feature Summary

• Features AND-gated serial inputs that permit complete control over incoming data entry
• Includes an asynchronous clear input for immediate reset of all registers
• Provides fully buffered clock and serial inputs to ensure signal integrity

Shift Registers Applications

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

Shift Registers Procurement Notes

Verify the NRND status indicated in the packaging addendum before finalizing design-in decisions. Confirm RoHS compliance and lead finish specifications match project requirements. Ensure the SOIC-14 footprint aligns with existing PCB layout constraints. Review thermal resistance values for adequate heat dissipation under maximum load conditions.

Shift Registers Selection Notes

Select this component when an 8-bit serial-to-parallel conversion is required with low power consumption. The wide operating voltage range supports various logic families. Verify that the asynchronous clear functionality meets system reset timing needs. Consider the SOIC package dimensions for space-constrained surface-mount applications.

Shift Registers Part Context

This part belongs to the SNx4HC164 series of 8-bit parallel-out serial shift registers manufactured by Texas Instruments. It shares functional characteristics with other variants in the family but differs in packaging and specific ordering suffixes. The device is designed for general-purpose digital logic applications requiring reliable data shifting capabilities.

Shift Registers Replacement Considerations

SN74HC164DR and SN74HC164DRG4 are listed as active production alternatives in the same SOIC-14 package. Verify pin compatibility and electrical specifications before substitution.
