ICC2
VIH = 2.4V (TTL), After 1 memory cycle,
RAS and CAS high
ICC3
VIH = Vcc - 0.05V (CMOS), After 1 memory
cycle, RAS and CAS high
Average Page Current 2
ICC4 RAS low, CAS cycling

* Valid data is presented at the outputs after all access times are satisfied but can go from the high-impedance
state to an invalid-data state prior to the specified access times as the outputs are driven when CAS goes low.
1. tOFF and tOEZ are specified when the outputs are no longer driven. The outputs are disabled by bringing either
OE or CAS high.
