SN74LV165APWRG3

Shift Registers Overview

The SN74LV165APWRG3 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 a clock-inhibit function and 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 the component matches the exact part number SN74LV165APWRG3. Confirm the package type corresponds to TSSOP-16 as indicated by the PW suffix. Ensure the revision level aligns with the latest datasheet SCLS402O or later. Check for RoHS compliance markers consistent with the G3 suffix designation.

Shift Registers Selection Notes

Select this component when expanding digital input capacity for microcontrollers. It is suitable for systems requiring parallel-to-serial conversion within the 2 V to 5.5 V supply range. Consider its low-drive characteristics if output ringing is a concern in bus interface applications.

Shift Registers Part Context

This device belongs to the SN74LV165A family of parallel-load 8-bit shift registers. It is manufactured by Texas Instruments and falls under the logic integrated circuit category. The specific ordering suffix indicates the TSSOP-16 package and lead-free composition.

Shift Registers Replacement Considerations

Direct substitutes include SN74LV165ADBR and SN74LV165ADR, which share identical electrical specifications but utilize SSOP and SOIC packages respectively.
