74HC40105; 74HCT40105  
4-bit x 16-word FIFO register  
Rev. 3 — 25 September 2013  
Product data sheet  
1. General description  
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 detects the state of the preceding flip-flop and  
communicates its own status to the succeeding flip-flop. When a control flip-flop is in the  
logic 0 state and sees a logic 1 in the preceding flip-flop, it generates a clock pulse. The  
clock pulse transfers data from the preceding four data latches into its own four data  
latches and resets the preceding flip-flop to logic 0. The first and last control flip-flops have  
buffered outputs. All empty locations "bubble" automatically to the input end, and all valid  
data ripples through to the output end. As a result, the status of the first control flip-flop  
(data-in ready output - DIR) indicates if the FIFO is full. The status of the last flip-flop  
(data-out ready output - DOR) indicates whether the FIFO contains data. As the earliest  
data is removed from the bottom of the data stack (output end), all data entered later will  
automatically ripple toward the output. Inputs include clamp diodes that enable the use of  
current limiting resistors to interface inputs to voltages in excess of VCC  
.
