Product Description
Pericoms PI5C32200D is a 32-bit bus switch that features 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 56Ω nominal termination to VBIAS.
Applications
Provides GTL termination for busses in a Pentium II/Slot 1 two
processor environment with an empty slot.
