RON is 1000Ω typical connected to 1.5V VBIAS
Pericom’s PI5C32202 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
100Ω nominal termination to 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
Applications
Provides GTL termination for busses for three to four processor
Pentium II system with an empty Slot II.
