SN74LV164AD

Shift Registers Overview

The SN74LV164AD is an 8-bit serial-in, parallel-out shift register from Texas Instruments. It operates on a single power supply ranging from 2 V to 5.5 V and utilizes LV CMOS logic technology. The device features two serial data inputs (A and B) that are internally ANDed, along with a clear input for asynchronous reset. It is housed in a 14-pin TVSOP package and supports surface mount installation. The component functions as a counter shift register with a serial-to-parallel counting sequence.

Shift Registers Feature Summary

• Provides eight-bit serial-to-parallel data conversion capability
• Features dual serial inputs with internal ANDing functionality
• Supports asynchronous clearing of all flip-flops via dedicated control line

Shift Registers Applications

• General-purpose serial-to-parallel data conversion circuits
• LED display scanning systems requiring sequential bit output
• Digital signal processing interfaces needing data expansion

Shift Registers Procurement Notes

Verify the specific suffix 'AD' corresponds to the TVSOP-14 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to procurement. Ensure the ordering part number matches the required logic family specifications exactly.

Shift Registers Selection Notes

Select this component for designs requiring low-voltage operation down to 2 V. Consider the TVSOP-14 package constraints regarding thermal dissipation and board space. Verify that the input voltage levels remain within the specified limits relative to the chosen supply voltage to ensure reliable logic transitions.

Shift Registers Part Context

This device belongs to the SN74LV164A series of shift registers. It serves as a standard solution for expanding parallel outputs from serial data streams in consumer electronics and industrial control applications. The LV series offers improved performance over older bipolar technologies while maintaining compatibility with standard logic families.
