... 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 ...

... Consequently, any depth or width FIFO can be created of word widths in increments of 9. When expanding in depth, a composite FF must be created by ORing the FFs together. Likewise, a composite EF is created by ORing the EFs together. HF and RT functions are not available in depth expansion mode. CY7C419/21/25/29/ are in a high impedance condition 0 8 after a valid write ...
