8. Recommended operating conditions
9. Static characteristics
[1] All typical values are measured at V
CC
=5V; T
amb
=25C.
[2] This is the increase in supply current for each input that is at the specified TTL voltage level rather than V
CC
or GND.
[3] Measured by the voltage drop between the nA and the nBn terminals at the indicated current through the switch. The lowest voltage of
the two (nA or nBn) terminals determines the ON resistance.
Table 5. Operating conditions
All unused control inputs of the device must be held at V
CC
or GND to ensure proper device operation.
