SN74LV165ARGYR

Shift Registers Overview

The SN74LV165ARGYR is a parallel-load, 8-bit shift register from Texas Instruments designed for VCC operation between 2 V and 5.5 V. It features eight individual direct data inputs enabled by a low level at the shift/load (SH/LD) input. The device includes a clock-inhibit function and a complemented serial output (QH). It supports mixed-mode voltage operation on all ports and incorporates Ioff circuitry to disable outputs during partial-power-down mode, preventing damaging current backflow.

Shift Registers Feature Summary

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

Shift Registers Applications

• Increasing the number of inputs on a microcontroller

Shift Registers Procurement Notes

Verify the specific ordering suffix ARGYR corresponds to the VQFN package variant when sourcing. Confirm that the component meets RoHS compliance standards as indicated in the manufacturer documentation. Ensure the supply chain provides original manufacturer packaging to maintain device integrity and traceability throughout the procurement process.

Shift Registers Selection Notes

Select this component for designs requiring an 8-bit parallel-to-serial conversion with a compact footprint. The VQFN package suits space-constrained surface-mount layouts. Verify that the operating voltage range aligns with the system's power rails and that the thermal characteristics are sufficient for the intended application environment.

Shift Registers Part Context

This part belongs to the SN74LV165A family of parallel-load 8-bit shift registers. The RGY suffix specifically denotes the 16-pin VQFN package type. This family is engineered for low-voltage CMOS logic applications, providing reliable data shifting capabilities within standard industrial temperature ranges while maintaining compatibility with various digital interfaces.

Shift Registers FAQ

How does the SH/LD input control data loading?

Holding the SH/LD input at a low level enables the parallel inputs, allowing data to be loaded directly into the internal registers.

What is the function of the CLK INH pin?

The CLK INH pin serves as a clock inhibit input. When held high, it prevents the clock signal from triggering a shift operation, effectively pausing data movement through the register stages.
