Pericom’s PI5C32200 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.
RON is 56Ω typical connected to 1.5V VBIAS
Low Power......50µW
Switching Speed......7.5ns max.
Channel On Capacitance: 8pF
VCC Operating Range: +5V ± 5%
ESD > 2000V......Human Body Model
Packages available: 56-pin TSSOP (A)

Applications
Provides GTL termination for busses in a Pentium II/Slot 1 two
processor environment with an empty slot.
Notes:
When Enabled:
Ports Ax connect to VBIAS..A
Ports Ay connect to VBIAS..B
Where:
X = 0-3, 8-11, 16-19, 24-27
Y = 4-7, 12-15, 20-23, 28-31
