CMOS STATIC RAM 1MEG (128K x 8-BIT)
DC ELECTRICAL CHARACTERISTICS(1)
(VCC = 5.0V ± 10%, VLC = 0.2V, VHC = VCC – 0.2V)
Symbol
Parameter
ICC Dynamic Operating Current, CS2 ≥ VIH and
CS2 ≥ VIH and CS1 ≤ VIL, Outputs Open,
VCC = Max., f = fMAX(2)
ISB Standby Power Supply Current (TTL Level)
CS1 ≥ VIH or CS2 ≤ VIL, Outputs Open,
VCC = Max., f = fMAX(2)
ISB1 Full Standby Power Supply Current
(CMOS Level) CS1 ≥ VHC,
or CS2 ≤ VLC Outputs Open,
VCC = Max., f = 0(2), VIN ≤ VLC or VIN ≥ VHC
NOTES:
1.All values are maximum guaranteed values.
2.fMAX = 1/tRC (all address inputs are cycling at fMAX); f = 0 means no address input lines are changing.
