SN74LS166AN3

Shift Registers Overview

The SN74LS166AN3 is an 8-bit parallel-load shift register from the Texas Instruments SN74LS series. It features serial-in and parallel-load capabilities, converting parallel data to serial output. The device operates within a supply voltage range of 4.75 V to 5.25 V. It utilizes bipolar logic technology and exhibits a propagation delay of 25 ns. Designed for through-hole mounting, it is available in a PDIP-16 package. The component supports a maximum operating temperature of +70 °C and a minimum of 0 °C.

Shift Registers Feature Summary

• Parallel-load capability allows simultaneous data entry into all eight stages
• Serial input enables cascading with other shift registers for extended data handling
• Asynchronous reset function clears all outputs regardless of clock state

Shift Registers Applications

• Data acquisition systems requiring parallel-to-serial conversion
• Industrial control interfaces for status monitoring
• Communication equipment serial data transmission modules

Shift Registers Procurement Notes

Verify the specific suffix 'AN3' against the manufacturer's official documentation to confirm pinout compatibility and electrical characteristics. Ensure the procurement source provides valid traceability for the SN74LS logic family specifications. Cross-reference the datasheet revision date to guarantee alignment with current industry standards for bipolar shift registers.

Shift Registers Selection Notes

Select this component when an 8-bit parallel-load shift register with LS speed is required. It is suitable for applications needing asynchronous reset and through-hole integration. Compare performance metrics such as propagation delay and power consumption against alternative LS series devices to ensure system compatibility and optimal signal integrity in digital logic circuits.

Shift Registers Part Context

This part belongs to the SN74LS166 family of parallel-load 8-bit shift registers manufactured by Texas Instruments. The LS designation indicates Low-power Schottky bipolar technology, offering a balance between speed and power dissipation. The AN3 suffix typically denotes specific packaging or testing variations within the standard industrial grade product line.

Shift Registers Replacement Considerations

SN74LS166AN is the direct equivalent without the suffix variation. SN74HC166PW offers similar functionality but uses HC CMOS technology with different voltage ranges and package types.
