Overview
The 74HC164D-Q100J is an 8-bit serial-in, parallel-out shift register produced by Nexperia USA Inc. This device is part of the 74HC series and is qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1), making it suitable for use in automotive applications. It features two serial data inputs (DSA and DSB) and eight parallel data outputs (Q0 to Q7), allowing data to be entered serially and shifted on the LOW-to-HIGH transitions of the clock (CP) input. The device also includes an asynchronous master reset input (MR) that clears the register and forces all outputs LOW.
