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.

The RON vs VIN curve shows the effect of ON-resistance and input voltage which is exponential. Ideally an input voltage between 0.2V and 3.6V will keep RON in the flat part of the curve (∆RON or flatness is ~2ohm). The logic control inputs can be driven up to +5.5V regardless of the supply voltage. For example, given a +5.0V supply, E may be driven low to 0V and high to 5.5V. Driving E Rail-to-Rail® minimizes power consumption. Power-Supply Sequencing Proper power-supply sequencing is recommended for all CMOS devices. Always apply VCC before applying signals to the input/ output or control pins. 5V VIO VIO 3V PI5AL102 PI5AL102 Enable 5V Enable 3.3V 1 kΩ From cPCI Connector 10Ω 2.7 kΩ Pericom PCI Bridge PI7C7100 Pullup Required on Each cPCI Line Figure 1.
