1. Stresses greater than those listed under ABSOLUTE 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

NOTES:
1. Typical values are at VCC = 5.0V, TA = 25°C.
2. Max value is guaranteed but not production tested.
3. 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.
4. The bus switch contributes no group delay other than the RC delay of the ON resistance of the switch and load capacitance. Group delay of the bus
switch, when used in a system, is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven
side.
