WRITE CYCLE SWITCHING CHARACTERISTICS
Symbol
Notes:
1. Test conditions assume signal transition times of 5 ns or less, timing reference levels of 0.9V/1.5V, input pulse levels of 0.4 to
2. The internal write time is defined by the overlap of CS1 LOW, CS2 HIGH and UB or LB, and WE LOW. All signals must be in valid states to initiate a Write, but
3. Tested with the load in Figure 2. Transition is measured ±100 mV from steady-state voltage. Not 100% tested.

WRITE CYCLE NO. 1
Notes:
1. WRITE is an internally generated signal asserted during an overlap of the LOW states on the CS1 , CS2 and WE inputs and at
2. WRITE = (CS1) [ (LB) = (UB) ] (WE).
