AC Electrical Characteristics
NOTES: 1. The operating temperature (TA) is guaranteed with transverse air flow exceeding 400 linear feet per minute.
2. WE is HIGH for read cycles.
3. If the CE LOW transition occurs coincident with or after the WE LOW transition, outputs remain in a high impedance
state.
4. If the CE HIGH transition occurs coincident with or after the WE HIGH transition, outputs remain in a high impedance
state.
5. If OE is HIGH during a write cycle, the outputs are in a high-impedance state during this period.
6. The following parameters are measured using the load shown in Figures 1 and 2.
(A) tCOE, tOEE, tBE, tOEW .....Output Enable Time
(B) tCOD, tODO, tBD, tODW ....Output Disable Time
