SN74LV166ANS

Shift Registers Overview

The SN74LV166ANS is an octal parallel-load shift register from Texas Instruments, utilizing low-voltage CMOS technology. It operates within a supply voltage range of 2 V to 5.5 V and features serial/parallel-to-serial data conversion. The device is housed in a 16-pin SOIC package and supports an operating temperature range from -40 °C to +85 °C.

Shift Registers Feature Summary

• Supports simultaneous parallel loading of eight bits or serial shifting via a dedicated clock input.
• Features asynchronous master reset functionality to clear all stored data independently of the clock signal.
• Provides complementary serial outputs for versatile interfacing with downstream logic circuits.

Shift Registers Applications

• Data acquisition systems requiring parallel-to-serial conversion
• Input expansion for microcontroller-based embedded designs
• Digital communication interfaces handling serial data streams

Shift Registers Procurement Notes

Verify the specific suffix 'ANS' against the manufacturer's official documentation to confirm the exact package type and tape-and-reel configuration. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet revision date to confirm technical specifications match your design constraints before finalizing procurement orders.

Shift Registers Selection Notes

Select this component when low-voltage operation between 2 V and 5.5 V is required. The SN74LV166ANS offers high-speed performance suitable for modern digital systems. Consider the SOIC-16 package for surface-mount assembly compatibility. Evaluate power consumption benefits compared to standard TTL alternatives for battery-powered applications.

Shift Registers Part Context

This part belongs to the SN74LVxxxA series of low-voltage logic devices. It serves as a functional equivalent to older bipolar technologies but with improved power efficiency. The octal shift register architecture allows for efficient data management in complex digital circuits requiring serial interface capabilities.

Shift Registers Replacement Considerations

Check for direct pin-compatible substitutes such as the SN74HC166 or SN74LVC166A. Verify voltage level compatibility and propagation delay differences. Ensure the alternative device supports the same 2 V to 5.5 V operating range and maintains identical package dimensions for seamless board integration.
