* Measured by the voltage drop between the A and B terminals at the indicated current through the switch.
On-state resistance is determined by the lower of the voltages of the two (A or B) terminals.
E This is the increase in supply current for each input that is at the specified TTL voltage level rather the V or GND.

ApplicationsInformation
LogicInputs
The logic control inputs can be driven up to +5.5V regardless of
the supply voltage. For example, given a +5.0V supply, IN may
be driven low to 0V and high to 5.5V. Driving IN Rail-to-Rail
supply may be seen at the device input pins during Hot Inser-
tion.ThePI5Cxxxxdeviceshavemaximumlimitsof7Vand120mA
for 20ns. If the power is higher or applied for a longer period of
time or repeatedly reaches the maximum limits the devices can be
damaged.
