LOCK pin description rewritten for clarity.
Changed suggested open-drain termination networks to
reflect more realistic operating conditions with reduction in
DC power consumption.
Added figure for typical power supply current at hot tempera-
ture to aid thermal analysis.
All outputs now specified with standard 50 pF test loads to
agree with actual test methodology.
ICC max specification reduced:
WAS:
375 mA
420 mA
480 mA
Figures 7, 8, 9, 23, 24, 25 and 26 have also been changed
accordingly.
25 MHz operation extended to product in PQFP package. T
min. improved at all frequencies from 0 ns to 2 ns and T
max. improved from 20 ns to 18 ns.

Redrawn for clarity. CLK signal drawn with more likely phase
relationship to CLK2. Open-drain output signals drawn to
show correct inactive states.
Deleted all references to 10 MHz. Intel no longer offers a
10 MHz 80960KB device.
