Note c: Bringing E high will not produce standby currents until any nonvolatile cycle in progress has timed out. See MODE SELECTION table.
Note e: Parameter guaranteed but not tested.
Note f: NE must be high during entire cycle.
Note g: For READ CYCLE #1 and #2, W and NE must be high for entire cycle.
Note h: Device is continuously selected with E low and G low.
Note i: Measured ± 200mV from steady state output voltage.
