SN74ALS164ANS

Shift Registers Overview

The SN74ALS164ANS is an 8-bit serial-in, parallel-out shift register from the Texas Instruments ALS logic family. It operates on a single supply voltage ranging from 4.5 V to 5.5 V and features asynchronous reset functionality triggered by a low-level signal. The device utilizes positive-edge clocking for data shifting and includes dual data inputs (A and B) that are internally ANDed. Packaged in a 14-pin SOIC surface-mount format, it supports unidirectional data flow with standard TTL-compatible outputs.

Shift Registers Feature Summary

• Serial-to-parallel data conversion capability using a single clock edge
• Asynchronous reset mechanism to clear all storage elements immediately
• Dual input configuration with internal AND gating for flexible control

Shift Registers Applications

• Data acquisition systems requiring serial-to-parallel conversion
• LED display drivers for scanning applications
• General-purpose digital logic sequencing circuits

Shift Registers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment against the SOIC-14 specification. Ensure the ordering suffix matches the required temperature range and packaging style. Request relevant documentation such as RoHS compliance certificates and datasheets prior to finalizing procurement orders.

Shift Registers Selection Notes

Select this component when designing circuits requiring reliable 8-bit serial data expansion within standard TTL voltage limits. Consider the ALS series characteristics regarding speed and power consumption relative to other logic families. Evaluate the SOIC package suitability for the target PCB layout constraints and thermal management requirements during the design phase.

Shift Registers Part Context

This part belongs to the SN74ALS164A series of shift registers manufactured by Texas Instruments. It represents a specific variant within the broader ALS logic family, designed for high-speed operation with reduced power dissipation compared to earlier standards. The component serves as a fundamental building block for sequential logic applications in digital electronics.

Shift Registers Replacement Considerations

Cross-reference with SN74ALS164AD for alternative packaging options within the same functional family. Verify compatibility with SN74ALS164ANE if through-hole mounting is required instead of surface mount technology.
