Unit Power Supply Voltage VCC 4.5 5.5 V Input Low Voltage VIL -2 V at Pulse Width 10 ns permitted -0.3 0.8 V Input High Voltage VIH 2.2 VCC+0.3 V b: ICC1 and ICC3 are dependent on output loading and cycle rate. The specified values are obtained with outputs unloaded. The current ICC1 is measured for WRITE/READ - ratio of 1/2. c: ICC2 is the average current requird for the duration of the STORE cycle (STORE Cycle Time). d: Bringing E ≥ V IH will not produce standby current levels until any nonvolatile cycle in progress has timed out. See MODE SELECTION table. The current ICC(SB)1 is measured for WRITE/READ - ratio of 1/2. |
