SN74166N3

Shift Registers Overview

The SN74166N3 is a parallel-load 8-bit shift register from Texas Instruments, utilizing standard TTL technology. It operates within a voltage range of 4.75V to 5.25V, with a nominal supply of 5V. The device features a maximum propagation delay of 23ns at nominal voltage and supports a maximum frequency of 35MHz. It is designed for an operating temperature range of 0°C to 70°C. Key electrical characteristics include a maximum input current of 0.051mA and a low-level output current capability of 40mA.

Shift Registers Feature Summary

• Parallel-load architecture allows simultaneous data entry across all eight bits.
• Serial output capability enables cascading for extended data handling.
• Clock inhibit function provides control over data shifting operations.

Shift Registers Applications

• Data storage in digital systems
• Serial-to-parallel conversion
• Parallel-to-serial conversion

Shift Registers Procurement Notes

Verify the specific suffix 'N3' against official Texas Instruments documentation to confirm package type and compliance status. Ensure the component matches the required TTL logic family specifications. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with parallel load functionality is required. Consider the 5V TTL compatibility and the 0°C to 70°C commercial temperature range. Evaluate the 40mA output drive capability against load requirements. Confirm that the serial-in/parallel-out or parallel-in/serial-out configuration meets the system's data flow needs.

Shift Registers Part Context

The SN74166 series belongs to Texas Instruments' standard logic product line, specifically designed for shift register applications. This family offers reliable performance for general-purpose digital logic tasks. The N3 suffix typically denotes a specific package variant, often related to lead-free or specific manufacturing standards, distinct from the base SN74166 model.

Shift Registers Replacement Considerations

Check for direct equivalents such as the SN74166N or other SN74LS164 variants if pin compatibility differs. Verify functional equivalence regarding clock inhibit and parallel load signals. Ensure replacement parts meet the same voltage and temperature specifications.
