P. 6 Publication Date: SEP. 2002 Revision:0.F tm TE CH Preliminary T14L1024A Notes: 1. During this period, I/O pins are in the output state, so input signals of opposite phase to the outputs should not be applied. 2. The data output from D OUT are the same as the data written to D IN during the write cycle. 3. D OUT provides the read data for the next address. 4. Transition is measured ± 500 mV from steady state with C L = 5pF. guaranteed but not 100% tested. This parameter is 5. If OE is low during a WE controlled write cycle, the write pulse width must be the larger of tWP or (tWHZ + tDW) to allow the I/O drivers to turn off and data to be placed on the bus for the required tDW. If OE is high during a WE controlled write cycle, this requirement does not apply and the write pulse can be as short as the specified tWP.
