-005 LOCK
pin description rewritten for clarity.
2.3. Connection Recommenda-
tions (pg. 11)
-005 Changed suggested open-drain termination networks to reflect
more realistic operating conditions with reduction in DC power
consumption.
Figure 9. Typical Current vs.
Frequency (Hot Temp) (pg. 13)
-005 Added figure for typical power supply current at hot
temperature to aid thermal analysis.
Figure 12. Test Load Circuit for
Three-State Output Pins (pg. 14)
Figure 13. Test Load Circuit for
Open-Drain Output Pins (pg. 14)
-005 All outputs now specified with standard 50 pF test loads to
agree with actual test methodology.
2.7. DC Characteristics (pg. 15) -005 ICC max specification reduced:
WAS: IS: AT:
375 mA 315 mA 16 MHz
420 mA 360 mA 20 MHz
480 mA 420 mA 25 MHz
Figures 7, 8, 9, 23, 24, 25 and 26 have also been changed
accordingly.
2.8. AC Specifications (pg. 16) -005 25 MHz operation extended to product in PQFP package. T

26ns 23ns 20 MHz
24ns 23ns 25 MHz
Functional Waveforms -005 Redrawn for clarity. CLK signal drawn with more likely phase
relationship to CLK2. Open-drain output signals drawn to show
correct inactive states.
Various -005 Deleted all references to 10 MHz. Intel no longer offers a
10 MHz 80960KB device.

Revision -008
To address the fact that many of the package prefix variables have changed, all package
prefix variables in this document are now indicated with an "x".
