SN74LV165APWR

Shift Registers Overview

The SN74LV165APWR is a parallel-load, 8-bit shift register from Texas Instruments designed for VCC operation between 2 V and 5.5 V. It features balanced CMOS push-pull outputs and supports mixed-mode voltage operation on all ports. The device includes clock-inhibit functionality and a complemented serial output (QH). It is fully specified for partial-power-down applications using Ioff circuitry to prevent damaging current backflow when powered down.

Shift Registers Feature Summary

• Supports mixed-mode voltage operation across all ports
• Includes Ioff circuitry for partial-power-down mode
• Features balanced CMOS push-pull outputs

Shift Registers Applications

• Increase the number of inputs on a microcontroller

Shift Registers Procurement Notes

Verify that the ordering suffix 'PW' corresponds to the TSSOP-16 package as documented in the manufacturer's datasheet. Confirm the specific revision level matches project requirements. Ensure supply voltage ranges align with system specifications before procurement.

Shift Registers Selection Notes

Select this component for designs requiring parallel-to-serial conversion within the 2 V to 5.5 V range. Consider the TSSOP-16 package constraints and thermal characteristics. Verify input transition rates meet recommended operating conditions to prevent oscillation.

Shift Registers Part Context

This part belongs to the SN74LV165A family of parallel-load 8-bit shift registers. It is manufactured by Texas Instruments and utilizes LV logic technology. The device is available in multiple packages, with the PW suffix indicating the TSSOP variant.

Shift Registers Replacement Considerations

Check for SN74LV165AD or SN74LV165ADR if SOIC packaging is required instead of TSSOP. Verify pin compatibility and electrical specifications against alternative sources.
