WRITE CYCLE SWITCHING CHARACTERISTICS
Notes:
1. Test conditions assume signal transition times of 3 ns or less, timing reference levels of 1.5V, input pulse
2. Tested with the load in Figure 2. Transition is measured 500 mV from steady-state voltage. Not 100% tested.
3. The internal write time is defined by the overlap of

in valid states to initiate a Write, but any one can go inactive to terminate the Write. The Data Input Setup and
Hold timing are referenced to the rising or falling edge of the signal that terminates the write.
