74HC/HCT40105 4-bit X 16-word FIFO Register

The 74HC/HCT40105 are high-speed Si-gate CMOS devices and are pin compatible with the "40105" of the "4000B" series. They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT40105 are first-in/first-out (FIFO) "elastic" storage Registers that CAN store sixteen 4-bit words. The "40105" is capable of handling 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 "1" signifies that the position,s data is filled and a "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 "0" state and sees a "1" in the preceding Flip-Flop it generates a Clock pulse that transfers data from the preceding four data Latches into its own four data Latches and resets the preceding Flip-Flop to "0". The first and last control Flip-Flops have buffered outputs. Since all empty locations "bubble" automatically to the input end, and all valid data ripples through to the output end, the status of the first control Flip-Flop (data-in ready output - DIR) indicates if the FIFO is full, and the status of the last Flip-Flop (data-out ready output - DOR) indicates if 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.
