SN74LV164ADB

Shift Registers Overview

The SN74LV164ADB is an 8-bit parallel-out serial shift register from the Texas Instruments SN74LV164A family. It utilizes low-voltage CMOS technology and operates within a supply voltage range of 2 V to 5.5 V. The device features two data inputs (A and B) that are internally ANDed, allowing for flexible serial input configurations. Data shifts on the positive edge of the clock pulse, with outputs provided in parallel form. It includes an asynchronous clear function to reset all flip-flops. The component is housed in a surface-mount package suitable for automated assembly.

Shift Registers Feature Summary

• Low-voltage CMOS architecture supporting mixed-mode voltage operation
• Dual serial inputs (A and B) combined via internal AND gate
• Positive-edge triggered clocking mechanism
• Asynchronous clear functionality for immediate output reset

Shift Registers Applications

• General-purpose serial-to-parallel data conversion
• I/O expansion in embedded systems
• Status indication circuits requiring sequential bit loading
• Digital logic control interfaces

Shift Registers Procurement Notes

Verify the specific suffix 'DB' against official Texas Instruments documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with the target operating voltage range of 2 V to 5.5 V. Confirm RoHS compliance status through the manufacturer's current product information sheet before procurement.

Shift Registers Selection Notes

Select this component when low power consumption and wide voltage tolerance are required. The LV series offers faster switching speeds compared to standard LS logic while maintaining lower power dissipation. Consider the package availability and thermal characteristics if high-density PCB layouts are involved. Verify input signal levels match the CMOS thresholds for reliable operation across the full voltage range.

Shift Registers Part Context

This part belongs to the SN74LV164A family of 8-bit shift registers. It is designed as a successor to older bipolar technologies, offering improved performance metrics. The family is widely used in consumer electronics and industrial applications where reliable serial data handling is necessary. It complements other logic families by providing robust drive capabilities at reduced voltages.
