Overview
The 74HC164D14, manufactured by Diodes Incorporated, is an 8-bit serial-in/parallel-out shift register. This device is part of the 74HC family of standard logic integrated circuits. It features two serial data inputs (DSA and DSB) and eight parallel data outputs (Q0 to Q7), making it suitable for a variety of digital circuit applications. The shift register operates on the LOW-to-HIGH transitions of the clock (CP) input, and it includes a master reset (MR) input that asynchronously clears the register and sets all outputs to LOW.
