... 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. • ...
