NOTES
1
AC inputs during testing are driven at DV
DD
– 0.5 V for a Logic 1 and 0.45 V for a Logic 0. Timing measurements are made at V
IH
min for a Logic 1 and V
IL
max for
a Logic 0.
2
For timing purposes, a port pin is no longer floating when a 100 mV change from load voltage occurs. A port pin begins to float when a 100 mV change from the
loaded V
/V
level occurs.

C
for Port0, ALE,

outputs = 100 pF; C
for all other outputs = 80 pF unless otherwise noted.
