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.
