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 = 3.3V, TA = 25°C ambient and maximum loading.

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

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

by the lower of the voltages on the two (A,B) pins.

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

Notes:

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

2. Typical values are at VCC = 3.3V, +25°C ambient.

3. Per driven input (control input only); A and B pins do not contribute to ∆ICC.
