NOTES:

1. All typical values are at VCC = 5 V, Tamb = 25°C

2. This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND

3. 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.
