ProductDescription

The PI5L102L CompactPCI Hot Swap Pull-up switch is a Quad 1:2

multiplexer. It is designed to switch the 1V precharge bias voltage

and 10-kohm pull-up resistor connected to the CompactPCI bus

signals during Hot Swap. Each switch can connect eight inputs

In addition, the PI5L102 can be used to select 2.7 kohms/3.3V or

1.0 kohm/5V pull-ups for the system card PCI signal lines.

ON resistance is a low 7 ohms maximum and all eight switches are

selectedordisabledwithasingleCMOS/TTLcompatiblesignal.For

general-purpose applications, the PI5L102 can replace mechanical

relays. In network systems, physical layer signals can be switched.

To reduce the insertion loss, the PI5L102 can be powered by a 6.2V

Zener diode.
