Product Description
Pericoms PI5C32203 is a 32-bit bus switch. Industry leading
advantages include very low power, and low I/O capacitance.
When the bus switch is enabled (ENx = 0), it is terminated
internally through a series resistor to an external VBIAS. The ON-
resistance of the switch along with the series resistor provides a
150
nominal termination to VBIAS.
Applications
Provides GTL termination for busses for five to six processor
Pentium II system with an empty Slot II.

= 3.3V, +25C ambient and maximum loading.
Note:
Stresses greater than those listed under MAXIMUM RATINGS may cause per-
manent damage to the device. This is a stress rating only and functional opera-
tion of the device at these or any conditions above those indicated in the opera-
tional sections of this specification is not implied. Exposure to absolute maxi-
mum rating conditions for extended periods of time may affect reliability.
