High Speed CMOS Logic 4-Bit X 16-Word FIFO Register

The Harris CD74HC40105 and CD74HCT40105 are high- speed silicon-gate CMOS devices that are compatible, except for shift-out circuitry, with the Harris CD40105B. They are low-power rst-in-out (FIFO) elastic storage Registers that CAN store 16 four-bit words. The 40105 is capable of handling input and output data at different shifting rates. This feature makes particularly useful as a Buffer between asynchronous systems. Each work position in the Register is clocked by a control ip- op, which stores a marker bit. A 1 signies that the posi- tions data is lled and a 0 denotes a vacancy in that posi- tion. The control ip-op detects the state of the preceding ip-op and communicates its own status to the succeeding ip-op. When a control ip-op is in the 0 state and sees a 1 in the preceeding ip-op, it generates a Clock pulse that transfers data from the preceding four data Latches into its own four data Latches and resets the preceding ip-op to 0. The rst and last control ip-ops have buffered outputs. Since all empty locations bubble automatically to the input end, and all valid data ripple through to the output end, the status of the rst control ip-op (DATA-IN READY) indicates if the FIFO is full, and the status of the last ip-op (DATA- OUT READY) indicates if the FIFO contains data. As the earliest data are removed from the bottom of the data stack (the output end), all data entered later will automatically propagate (ripple) toward the output. By Texas Instruments
