An initial pause of 200us is required after power-up followed by any 8 RAS-only or CAS-before-RAS refresh cycles before proper device operation is achieved. 2. VIH(min) and VIL(max) are reference levels for measuring timing of input signals. Transition times are measured between VIH(min) and VIL(max) and are assumed to be 5ns for all inputs. 3. Measured with a load equivalent to 2 TTL loads and 100pF. 4. Operation within the tRCD(max) limit insures that tRAC(max) can be met. tRCD(max) is specified as a reference point only. If tRCD is greater than the specified tRCD(max) limit, then access time is controlled exclusively by tCAC. 5. Assumes that tRCDtRCD(max). 6. This parameter defines the time at which the output achieves the open circuit condition and is not referenced to VOH or VOL. 7. tWCS is non-restrictive operating parameter. It is included in the data sheet as electrical characteristics only. If tWCStWCS(min), the cycle is an early write cycle and the data out pin will remain high impedance for the duration of the cycle. 8. Either tRCH or tRRH must be satisfied for a read cycle. 9. These parameter are referenced to the CAS leading edge in early write cycles and to the W leading edge in read-write cycles. 10. Operation within the tRAD(max) limit insures that tRAC(max) can be met. tRAD(max) is specified as reference point only. If tRAD is greater than the specified tRAD(max) limit, then access time is controlled by tAA. 11. tCEZ(max), tREZ(max), tWEZ(max) and tOEZ(max) define the time at which the output achieves the open circuit condition and are not referenced to output voltage level. 12. If RAS goes to high before CAS high going, the open circuit condtion of the output is achieved by CAS high going. If CAS goes to high before RAS high going, the open circuit condtion of the output is achieved by RAS high going. 13. tASCtCP min 14. In order to hold the address latched by the first CAS going low, the parameter tCLCH must be met.
