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 = 5.0V, TA = 25°C ambient and maximum loading.

3. On 1AN and 1BIN (Data Input) pins only.

4. Measured by the voltage drop between I and Y pin at indicated current through the switch. ON resistance is determined

by the lower of the voltages on the two (I,Y) pins.

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