Description

Table 3. 80960KA Pin Description:

L-Bus Signals (pg. 8)

-004

LOCK pin description rewritten for clarity.

2.3. Connection Recommenda-

tions (pg. 11)

-004

Changed suggested open-drain termination networks to

reflect more realistic operating conditions with reduction in

DC power consumption.

Figure 9. Typical Current vs. Fre-

quency (Hot Temp) (pg. 13)

-004

Added figure for typical power supply current at hot tempera-

ture 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)

-004

All outputs now specified with standard 50 pF test loads to

agree with actual test methodology.

2.7. DC Characteristics (pg. 15)

-004

ICC max specification reduced:

Figures 7, 8, 9, 23, 24, 25 and 26 have also been changed

accordingly.

2.8. AC Specifications (pg. 16)

-004

25 MHz operation extended to product in PQFP package. T8

min. improved at all frequencies from 0 ns to 2 ns and T8

max. improved from 20 ns to 18 ns.

Functional Waveforms

-004

Redrawn for clarity. CLK signal drawn with more likely phase

relationship to CLK2. Open-drain output signals drawn to

show correct inactive states.
