ELECTRICAL CHARACTERISTICS AND RECOMMENDED DC OPERATING CONDITIONS (-55oC < T A < +125oC & -40oC < T A < +85oC ; Vcc = 5V +10%) PARAMETER SYMBOL MIN MAX UNITS Input Leakage Current (any input 0<VIN<VIN+0.5V, all other input pins not under test = 0 Volt) II(L) -5 5 uA Output Leakage Current (Data out is disabled, 0V<VOUT<VCC) IO(L) -5 5 uA Output High Voltage (IOH = -5mA) VOH 2.4 --- V Output Low Voltage (IOL = 4.2mA) VOL --- 0.4 V -60 -70 ICC1* Operating Current (RAS\ and CAS\, Address cycling @ tRC = MIN), Power = Don't Care 110 100 mA ICC2 Standby Current (RAS\ = CAS\ = W\ = VIH) Power = Normal L 33 mA ICC3* RAS\-only Refresh Current (CAS\ = VIH, RAS\, Address cycling @ tRC = MIN), Power = Don't Care 110 100 mA ICC4* Fast Page Mode Current (RAS\ = VIL, CAS\, Address cycling @ tPC = MIN), Power = Don't Care 90 80 mA ICC5 Standby Current (RAS\ = CAS\ = W\ = Vcc - 0.2V) Power = Normal L 22 mA ICC6* CAS\-BEFORE-RAS\ Refresh Current (RAS\ and CAS\ cycling @ tRC = MIN), Power = Don't Care 110 100 mA ICC7 Battery back-up current, Average power supply current, Battery back- up mode, Input high voltage (VIH) = VCC - 0.2V, Input low voltage (VIL) = 0.2V, CAS\ = 0.2V, DQ = Don't care, tRC = 62.5us (2K/L-ver), tRAS = tRAS min ~ 300ns 11 mA ICCS Self Refresh Current, RAS\ = CAS\ = 0.2V, W\ = OE\ = A0 ~ A11 = VCC - 0.2V or 0.2V, DQ0 ~ DQ3 = VCC - 0.2V, 0.2V or Open 11 MAX SYMBOL PARAMETERS UNITS NOTES: *I CC1 , I CC3 , I CC4 and I CC6 are dependent on output loading and cycle rates. Specified values are obtained with the output open. I CC is specified as an average current. In I CC1 , I CC3 , and I CC6 address can be changed maximum once while RAS\ = V IL . In I CC4 , address can be changed maximum once within one fast page mode cycle time, t PC . |
