RON is 75Ω typical connected to 1.5V VBIAS
Pericoms PI5C32201 is a 32-bit bus switch that features very low
power, and low I/O capacitance. When the bus switch is enabled
(ENx = Low), 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 75Ω nominal termination to VBIAS.
LowPower......50µW
SwitchingSpeed......7.5nsmax.
Channel On Capacitance: 8pF
VCC OperatingRange:+5V±5%
ESD>2000V......HumanBodyModel
Packagesavailable:56-pinTSSOP(A)
Applications
Provides GTL termination for busses for two to three processor
Pentium II system with an empty Slot II.
