A Write occurs during the overlap (tWP) of a low CE1, a high CE2 and a low W E . tWR is measured from the earliest of CE1 or W E going high or CE2 going low to the end of the Write cycle. If the CE1 low transition or the CE2 high transition occurs simultaneously with the W E low transition or after the W E transition, outputs remain in a high impedance state. 5. tCW is measured from the later of CE1 going low or CE2 going high to the end of Write. 6.
