te ch tm t14l1024n tm technology inc. reserves the right p. 8 publication date: apr. 2002 to change products or specifications without notice. revision: c 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. this parameter is guaranteed but not 100% tested. 5. if oe is low during a we controlled write cycle, the write pulse width must be the larger of t wp or (t whz + t dw ) to allow the i/o drivers to turn off and data to be placed on the bus for the required t dw . 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 t wp .
