SN74LV166APWRG4

Shift Registers Overview

The SN74LV166APWRG4 is an 8-bit parallel-load shift register from Texas Instruments, belonging to the LV logic series. It operates on a single CMOS circuit with serial/parallel-to-serial counting order. The device is housed in a TSSOP-16 package and supports a supply voltage range of 2 V to 5.5 V. It functions within a temperature range of -40°C to +85°C. Propagation delays are specified at 23.3 ns, 18.9 ns, and 11.9 ns. The component features five input lines and complies with RoHS standards.

Shift Registers Feature Summary

• Supports parallel data loading for rapid initialization of shift register states
• Enables serial output shifting for efficient data transmission across limited pins
• Operates with wide supply voltage compatibility for flexible system integration

Shift Registers Applications

• Data acquisition systems requiring parallel-to-serial conversion
• Industrial control interfaces for status bit scanning
• Communication modules handling serial data streams

Shift Registers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and halogen-free compliance as per manufacturer documentation. Confirm the TSSOP-16 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Check for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with parallel load capability is required within the LV logic family. It is suitable for designs needing operation between 2 V and 5.5 V. Consider the propagation delay specifications for timing-critical applications. Verify that the TSSOP-16 package is compatible with your assembly process and board space constraints.

Shift Registers Part Context

This part belongs to the SN74LV166A family of 8-bit parallel-load shift registers. It shares functional similarities with other members like the SN74HC166A but differs in speed and voltage characteristics. The LV series offers faster performance than standard HC logic while maintaining CMOS input compatibility. It is designed for general-purpose digital signal processing tasks.

Shift Registers Replacement Considerations

The SN74LV166AD is a comparable variant within the same family. Verify pinout compatibility and electrical parameter alignment before substitution. Ensure the replacement part meets the same voltage and temperature requirements.
