The Cx output will go HIGHwithin tHLCH from the falling edge of Hx, or Cx willgo LOW within tMLCL from the falling edge of Mx.All Mx and Hx inputs must be HIGH during a validcompare cycle.FORCE HIT OR MISS CYCLE TIMINGElectrical Characteristics and Recommended AC Operating Conditions(O"CsTAs70"C) (Vcc = 5.0 ± 10%)STD ALTSYM SYM PARAMETER MINtHLCH tHA Hx to Force Hit Access TimetHHCZ tHHZ Hx to Compare High-ZtHL-CGX tHS Force Hit to CGx Don't Care 2tHH-CGH tHR Force Hit to CGX Recognized 2tMLCL tMA Mx to Force Miss Access TimetMHCZ tMHZ Mx to Compare to High-ZtML-CGX tMS Force Miss to CGx Don't CaretMH-CGH tMR Force Miss to CGx Recognized 2tMLHX tMHS Force Miss to Hx Don't Care 2tMHHH tMHR Force Miss To Hx Recognized 2MAX UNITS NOTES8 ns5 nsnsns8 ns5 ns2 nsnsnsns9/18373
