• Description: PC87200 PCI to ISA Bridge
• Manufacturer: NSC [National Semiconductor]

8.0 Electrical Characteristics
8.3 Electrical Connections
8.3.5 Unused Input Pins
All inputs not used by the system designer should be kept
at either ground or V
ation, connect active-high inputs to ground through a 20-
kohm ( 10%) pull-down resistor and active-low inputs to
V
8.3.6 NC-Designated Pins
Pins designated NC should be left disconnected. Connect-
ing an NC pin to a pull-up resistor, pull-down resistor, or an
active signal could cause unexpected results and possible
circuit malfunctions.
8.3.7 Power and Ground Connections and Decoupling
Testing and operating the PC87200 requires the use of
standard high frequency techniques to reduce parasitic

effects. These effects can be minimized by filtering the DC
power leads with low-inductance decoupling capacitors,
using low-impedance wiring, and by utilizing all of the V
and GND pins.
8.4 Absolute Maximum Ratings
Table 6. lists absolute maximum ratings for the PC87200.
Stresses beyond the listed ratings may cause permanent
damage to the device. Exposure to conditions beyond these lim-
its may (1) reduce device reliability and (2) result in prema-
ture failure even when there is no immediately apparent
sign of failure. Prolonged exposure to conditions at or near
the absolute maximum ratings may also result in reduced
useful life and reliability These are stress ratings only and
do not imply that operation under any conditions other than
those listed under Table 7. is possible.
