SN74LV165APW

Shift Registers Overview

The SN74LV165APW is a parallel-load, 8-bit shift register from the SN74LV165A series. It operates on a supply voltage (VCC) ranging from 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). Designed for surface-mount applications, it utilizes a 16-pin TSSOP package with dimensions of 5.00 mm by 4.40 mm.

Shift Registers Feature Summary

• Supports partial-power-down mode operation via Ioff circuitry that disables outputs to prevent damaging current backflow when powered down.
• Features latch-up performance exceeding 250 mA per JESD 17 standard specifications.
• Provides parallel-in access through eight individual direct data inputs enabled by a low level at the shift/load input.

Shift Registers Applications

• Increasing the number of inputs available on a microcontroller
• Bus interface type applications where output ringing is a concern
• Peripheral data loading gates in system controllers

Shift Registers Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the 16-pin TSSOP package configuration required for your design. Confirm that the component meets RoHS compliance standards as indicated in official documentation. Ensure that the selected variant aligns with the thermal and electrical requirements specified in the datasheet for your intended operating environment.

Shift Registers Selection Notes

Select this component when an 8-bit parallel-to-serial conversion capability is required within a 2 V to 5.5 V operational range. Consider the TSSOP package constraints regarding board space and thermal dissipation characteristics. Evaluate the need for mixed-mode voltage support if interfacing with different logic levels. Verify that the clock-inhibit function meets the timing requirements of your specific application architecture.

Shift Registers Part Context

This part belongs to the SN74LV165A family of parallel-load 8-bit shift registers manufactured by Texas Instruments. The LV series indicates Low-Voltage CMOS technology designed for compatibility with various digital logic families. The 'PW' suffix specifically denotes the Thin-Shrink Small-Outline Package (TSSOP), which offers a compact footprint suitable for high-density PCB layouts compared to larger SOIC or DIP alternatives.

Shift Registers Replacement Considerations

Consult the manufacturer's orderable addendum for alternative packages such as D (SOIC), DB (SSOP), or RGY (VQFN) that share identical internal functionality. Cross-reference with other manufacturers' equivalents only after verifying pinout compatibility and electrical parameter alignment with the original specification sheet.
