SN74LV165ADE4

Shift Registers Overview

The SN74LV165ADE4 is a parallel-load, 8-bit shift register from Texas Instruments. It operates on a supply voltage of 2 V to 5.5 V and supports mixed-mode voltage operation across all ports. The device features balanced CMOS push-pull outputs and includes clock-inhibit functionality alongside a complemented serial output (QH). It incorporates Ioff circuitry to disable outputs during partial-power-down modes, preventing damaging current backflow. The component is housed in a 16-pin SOIC package.

Shift Registers Feature Summary

• Supports mixed-mode voltage operation on all ports
• Includes Ioff circuitry for partial-power-down applications
• Features balanced CMOS push-pull outputs
• Provides clock-inhibit function and complemented serial output

Shift Registers Applications

• Increasing the number of inputs on a microcontroller

Shift Registers Procurement Notes

Verify that the ordering suffix 'E4' corresponds to the specific lead-free and environmental compliance requirements defined by Texas Instruments. Confirm the package type matches the required PCB footprint. Ensure the selected variant aligns with the intended operating temperature range and voltage specifications for the target application design.

Shift Registers Selection Notes

Select this component when an 8-bit parallel-to-serial conversion capability is required within a system utilizing 2 V to 5.5 V logic levels. Consider the SN74LV165A for designs needing mixed-voltage port support and partial-power-down isolation. Evaluate the 16-pin SOIC package dimensions against available board space constraints before finalizing the part selection.

Shift Registers Part Context

This device belongs to the SN74LV165A family of parallel-load 8-bit shift registers manufactured by Texas Instruments. The 'E4' suffix typically denotes lead-free packaging and RoHS compliance standards set by the manufacturer. The component is designed for general-purpose digital logic applications requiring data shifting and latching functions.

Shift Registers Replacement Considerations

Direct substitutes include other SN74LV165A variants such as SN74LV165AD or SN74LV165APW, provided they meet the same electrical and thermal specifications. Verify pin compatibility and package dimensions when considering alternative manufacturers' equivalents.
