Overview
The 74LV164D,118 is an 8-bit serial-in/parallel-out shift register produced by Nexperia USA Inc. This integrated circuit is designed to handle serial data input and convert it into parallel output, making it a versatile component in various digital circuit applications. The device features two serial data inputs (DSA and DSB) and eight parallel outputs (Q0 to Q7), allowing for flexible data entry and output configurations. The shift register operates on the LOW-to-HIGH transition of the clock input (CP) and includes a master reset input (MR) to clear the register and set all outputs to LOW.
