NOTES:

1. All typical values are at VCC = 5 V, Tamb = +25°C ambient and maximum loading.

2. Measured by the voltage drop between the A and the B terminals at the indicated current through the switch.

On-state resistance is determined by the lowest voltage of the two (A or B) terminals.

3. These parameters are determined by device characterization, but is not production tested.

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

5. Per TTL driven input (VI = 3.4 V, control inputs only); A and B pins do not contribute to ICC.

6. This current applies to the control inputs only and represent the current required to switch internal capacitance at the specified frequency.

The A and B inputs generate no significant AC or DC currents as they transition. this parameter is not tested, but is guaranteed by design.
