An initial pause of 200us is required after powerup followed by any 8 only or before refresh cycles before proper device operation is achieved. IH(min) and IL(max) are reference levels for measuring timing of input signals. Transition times are measured between IH(min) and IL(max) and are assumed to be 5ns for all inputs. Measured with a load equivalent to 2 TTL loads and 100pF. Operation within the D(max) limit insures that trac(max) can be met. D(max) is specified as a reference point only. If D is greater than the specified D(max) limit, then access time is controlled exclusively by tcac. Assumes that D D(max). This parameter defines the time at which the output achieves the open circuit condition and is not referenced to OH or OL. 8. 9. Either H or trrh must be satisfied for a read cycle. These parameter are referenced to the leading edge in early write cycles and to the leading edge in readwrite cycles. 10. Operation within the trad(max) limit insures that trac(max) 11. 12. 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. tcez(max), trez(max), tez(max) and tz(max) define the time at which the output achieves the open circuit condition and are not referenced to output voltage level. If goes to high before high going, the open circuit condtion of the output is achieved by high going. If goes to high before high going, the open circuit condtion of the output is achieved by high going. 13. tasc tcp min 7. tcs is nonrestrictive operating parameter. It is included in the data sheet as electrical characteristics only. If tcs tcs(min), the cycle is an early write cycle and the data out pin will remain high impedance for the duration of the cycle.
