NOTES:
1) AC measurements assume tT=1ns.
2) The reference level for timing of input signals is 1.4V.
3) This parameter is measured with a load circuit equivalent to 1 TTL load and 50pF
(RLoad is 50ohm).
4) An access time is measured at 1.4V.
5) If tT is longer than 1ns, the reference level for timing of input signals are VIH and VIL.
