Overview
The CD74AC164M96 is an 8-bit serial-in/parallel-out shift register produced by Texas Instruments. This device utilizes Advanced CMOS Logic technology and features asynchronous reset. It is designed with two serial inputs (A and B) connected through an AND gate, ensuring that both inputs must be high to set the input data line high. The device operates on a rising-edge triggered clock (CLK) and is capable of storing and propagating data through its registers upon each clock trigger.
