Fifo Register

The HCC40105B (extended temperature range) and HCF40105B (intermediate temperature range) are monolithic integrated circuits, available in16-lead dual in-line plastic or ceramic package. The HCC HCF40105B is a low-power first-in-first-out (FIFO) elastic storage Register that CAN store 16 4-bit words. It is capable of handling input and output data atdifferent shifting rates. This featuremakes itparticu- larly useful as a Buffer between asynchronous sys- tems. Each word position in the Register is clocked by a control Flip-Flop which stores a marker bit. A 1 sig- nifies that the positions data is filled and a0 denotes a vacancy in that position. The control Flip-Flop detects the state of the preceding Flip-Flop and communicates itsown status tothe succeeding Flip-Flop When a con- trol 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. By STMicroelectronics
