Working Principles

SN74AS194D is a 4-bit parallel-access shift register with serial input and output capabilities. It operates by shifting data through its internal flip-flops based on the clock signal. The parallel inputs are loaded into the register when the master reset (MR) input is activated. The shifted data can be accessed from the output pins (Q0-Q3) or their complementary counterparts (Q0'-Q3').
