DESCRIPTION

It is built around two basic cells. The first one (Cell 1) provides line termination, EMI filtering and ESD protection for the Strobe and Datalines while the second one (Cell 2) provides EMI filtering and ESD protection for the Control and Status lines. In addition, ST1284-xxA8 provides extra protection against ESD. When test...
