SN74LV164APWRG4

Shift Registers Overview

The SN74LV164APWRG4 is an 8-bit serial-in, parallel-out shift register from the Texas Instruments SN74LV164A series. It operates on a single CMOS logic family with a supply voltage range of 2 V to 5.5 V. The device features two serial data inputs (1A and 1B) that are internally ANDed, allowing for flexible cascading or gating control. It utilizes a single clock input to shift data into eight D-type flip-flops, providing complementary outputs. The component is housed in a 14-TSSOP package and supports mixed-mode operation, enabling interface between different voltage domains.

Shift Registers Feature Summary

• Supports mixed-mode voltage operation for interfacing diverse logic families

Shift Registers Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and manufacturing changes as per Texas Instruments documentation. Confirm the package type matches the design footprint requirements. Ensure the operating temperature range aligns with the intended environmental conditions. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.

Shift Registers Selection Notes

Select this component when an 8-bit serial shift register with complementary outputs is required within the LV logic family. It is suitable for applications needing a wide supply voltage range and mixed-mode compatibility. Consider the TSSOP-14 package constraints regarding board space and thermal dissipation. Evaluate the propagation delay specifications against the system clock speed requirements.
