Notes:
For condition shown as Min or Max use the appropriate values under recommended operating conditions.
1. All typical values are at V
2. Measured by the voltage drop between the A and B terminals at the indicated current through the switch.
On-state resistance is determined by the lower voltage of the two (A or B) terminals.
3. This is the increase in supply current for each input that is at the specified TTL voltage level rather than V
or GND.
