The 74HC40105; 74HCT40105 is a first-in/first-out (FIFO) "elastic" storage register that
can store 16 4-bit words. It can handle input and output data at different shifting rates.
This feature makes it particularly useful as a buffer between asynchronous systems. Each
word position in the register is clocked by a control flip-flop, which stores a marker bit. A
logic 1 signifies that the data at that position is filled and a logic 0 denotes a vacancy in
that position. The control flip-flop d
