Description
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 10k& pull-up resistor connected to the CompactPCI
bus signals during Hot Swap. Each switch can connect eight inputs
(I
An
to I
Dn
) to a given pull-up voltage level.
In addition, the PI5L102 can be used to select 2.7 k&/3.3V or
1.0 kohm/5V pull-ups for the system card PCI signal lines.
ON resistance is a low 7& maximum and all eight switches are
selected or disabled with a single CMOS/TTL compatible signal.
For general-purpose applications, the PI5L102 can replace me-
chanical 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.
