Product 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 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.

Note:

Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the device.
This is a stress rating only and functional operation of
the device at these or any other conditions above
those indicated in the operational sections of this
specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may
affect reliability.

Notes:

1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.

2. Typical values are at VCC = 6.2V, TA = 25°C ambient temperature.

3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.

4. Measured by voltage drop between I and Y pins at indicated current through the switch. ON resistance is determined by
the lower of the voltages on the two (I,Y) pins.

Note:

1. This parameter is determined by device characterization, but not production tested.

2. Switch ON Capacitance accounts for capacitance of both switch channels (IX0 & IX1) ON at one time.

Notes:

1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.

2. Typical values are at VCC = 6.2V, TA = 25°C ambient temperature.

3. Per TTL driven input (VIN = 3.4V, control inputs only); A and B pins do not contribute to ICC.

4. This current applies to the control inputs only and represent the current required to switch internal capacitance at the specified

Applications

VCC Bias Voltage vs R

ON

To keep RON to a minimum, it is recommended that the VCC voltage
be increased to a voltage between +6.0V and +6.5V (see Figure 5).
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
(∆R

ON

or flatness is ~2ohm).

Logic Inputs

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.
