SN74LV164ANSR

Shift Registers Overview

The SN74LV164ANSR is an 8-bit parallel-out serial shift register from the Texas Instruments SN74LV164A series. It utilizes low-voltage CMOS technology and operates within a supply voltage range of 2 V to 5.5 V. The device features two serial data inputs (A and B) that are internally ANDed, allowing for flexible serial input configurations. It includes a direct asynchronous clear input to reset all flip-flops to a low state independently of the clock signal. The component is housed in a 14-pin SOIC package and supports surface-mount installation.

Shift Registers Feature Summary

• Provides eight parallel outputs derived from serial data input via internal AND gating of dual inputs.
• Features a direct asynchronous clear function to reset outputs without clock dependency.
• Supports mixed-mode voltage operation across a wide supply voltage range.

Shift Registers Applications

• Serial-to-parallel data conversion in digital logic circuits
• General-purpose shift register applications requiring low-voltage operation
• Interface circuits connecting serial communication lines to parallel loads

Shift Registers Procurement Notes

Verify the specific ordering suffix ANSR confirms the SOIC-14 package and tape-and-reel packaging format. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Confirm the manufacturer date code aligns with your production timeline. Validate that the supply voltage specifications match your system design constraints before finalizing procurement.

Shift Registers Selection Notes

Select this component when an 8-bit shift register is required with low-voltage compatibility down to 2 V. The SN74LV164ANSR is suitable for designs needing asynchronous clearing and dual serial inputs. Consider the SOIC-14 package dimensions for PCB layout. Compare propagation delay characteristics against system timing requirements to ensure adequate performance margins.

Shift Registers Part Context

This part belongs to the SN74LV164A family of 8-bit parallel-out serial shift registers. The LV designation indicates low-voltage CMOS technology, offering broader operating voltage ranges compared to standard TTL counterparts. The series is designed for general-purpose digital logic applications requiring reliable serial data shifting capabilities.

Shift Registers Replacement Considerations

Compatible substitutes include other SN74LV164 variants with matching pinouts and electrical characteristics. Verify that alternative parts maintain the same asynchronous clear functionality and voltage specifications. Ensure package compatibility or adapter solutions are available if physical footprint changes occur.
