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 (IAn to IDn) to a given pull-up voltage level. 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 selected or disabled with a single CMOS/TTL compatible signal. 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.
