SN74LV165ADRG4

Shift Registers Overview

The SN74LV165ADRG4 is a parallel-load, 8-bit shift register from the Texas Instruments SN74LV165A family. 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 dedicated circuitry for partial-power-down applications via Ioff functionality. It provides eight individual direct data inputs enabled by a low level at the shift/load (SH/LD) input, allowing parallel access to each stage while shifting data toward the serial output QH.

Shift Registers Feature Summary

• Supports mixed-mode voltage operation on all ports
• Includes circuitry for partial-power-down mode using Ioff
• Features 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 'RGY' corresponds to the specific 16-pin VQFN package variant required for your design. Confirm that the component revision matches the current production data status. Ensure compatibility with the recommended operating conditions regarding supply voltage and temperature ranges before finalizing procurement.

Shift Registers Selection Notes

Select this component when an 8-bit parallel-to-serial conversion is needed within a system requiring 2 V to 5.5 V logic levels. The LV series is suitable for applications demanding mixed-voltage interface capabilities. Consider the VQFN package dimensions if board space is constrained. Verify that the clock frequency requirements align with the switching characteristics specified for the target supply voltage.

Shift Registers Part Context

This part belongs to the SN74LV165A family of parallel-load 8-bit shift registers manufactured by Texas Instruments. The family is designed for low-voltage CMOS applications. The 'RGY' suffix indicates a specific surface-mount package type, distinct from other variants like SOIC or SSOP found in the same product line.

Shift Registers Replacement Considerations

Check for SN74LV165ADBRG4 or SN74LV165APWRG4 if different package footprints are acceptable. Verify pinout compatibility before substituting.
