Notes:

1.

Typical values are specified at VCC = 5.0V and TA = 25

oC.

2.

RON is measured by forcing specified current into the ‘output’ node of the switch with the ‘input’ node of the switch at the the

specified voltage

Notes:

1.

For conditions shown as Min or Max, use the appropriate values per Recommended Operating Conditions.

2.

Per TTL-driven control input. All other control inputs at GND. Switch I/O pins do not contribute to

∆ICC.

3.

This parameter represents the average DC current resulting from the switching of internal nodes of the device at a given

frequency. The switch I/O pins make insignificant contribution to the dynamic power supply current of the device. This parameter

is guaranteed, but not production tested.
