Notes:

1. Test conditions assume signal transition times of 3 ns or less, timing reference levels of 1.3V, input pulse levels of 0.4V to 2.2V

and output loading specified in Figure 1.

2. The internal write time is defined by the overlap of CE LOW, and UB or LB, and WE LOW. All signals must be 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.

3. Tested with the load in Figure 2. Transition is measured ±500 mV from steady-state voltage. Not 100% tested.

Notes:

1. WRITE is an internally generated signal asserted during an overlap of the LOW states on the CS and WE inputs and at least

one of the LB and UB inputs being in the LOW state.

2. WRITE = (CS) [ (

LB) = (UB) ] (WE).
