74LV164DB,118

Overview

The 74LV164DB,118 is an 8-bit serial-in parallel-out shift register manufactured by Nexperia USA Inc. It belongs to the LV (Low Voltage) CMOS logic family and operates within a supply voltage range of 1 V to 5.5 V. The device features two serial data inputs (A and B) that are internally ANDed, providing a single serial input path for simplified interfacing. It includes a dedicated clear pin to reset all outputs to a low state. The component is housed in a 14-lead SO package (SOT108) suitable for surface mount technology applications.

Feature Summary

• Provides 8-bit serial-to-parallel data conversion capability
• Features dual serial inputs with internal ANDing function
• Operates across a wide supply voltage range from 1 V to 5.5 V
• Includes asynchronous clear functionality for immediate output reset

Applications

• General-purpose serial-to-parallel data expansion
