† _{See Figures 1 and 2.}
NOTE 2. TTL input signals are 0 to 3 V with less than 3 ns rise/fall times between 10% and 90% levels. ECL input signals are VDD – 1.8 V to
VDD – 0.8 V with less than 2 ns rise/fall times between 20% and 80% levels. For input and output signals, timing reference points are
at the 50% signal level. Analog output loads are less than 10 pF. D0 – D7 output loads are less than 40 pF.
