Overview
The 74HC164D,653 from Nexperia USA Inc. is an 8-bit serial-in, parallel-out shift register. This device is part of the 74HC series, known for its CMOS low power dissipation and high noise immunity. It is widely used in various electronic designs due to its versatility and reliability.
The 74HC164D features two serial data inputs (DSA and DSB) and eight parallel data outputs (Q0 to Q7). Data is entered serially through either DSA or DSB, and the device can be reset asynchronously using the master reset input (MR). The shift register operates on the LOW-to-HIGH transitions of the clock (CP) input, making it suitable for a range of digital circuit applications.
