... FIFOs to retransmit the data. Read enable (R) and write enable (W) must both be HIGH during retransmit, and then R is used to access the data. The CY7C419, CY7C420, CY7C421, CY7C424, CY7C425, CY7C428, CY7C429, CY7C432, and CY7C433 are fabricated using an advanced 0.65-micron P-well CMOS technology. Input ESD protection is greater than 2000V and latch-up is prevented by careful layout and guard rings ...

... FIFO and the full flag must be used to prevent writing into a full FIFO. For example, consider an empty FIFO that is receiving read pulses. Because the FIFO is empty, the read pulses are ignored by the FIFO, and nothing happens. Next, a single word is written CY7C419/21/25/29/33 after RTR . FIFOs can be CC ...
