All typical values are measured at V
CC
= 5 V; T
amb
= 25 °C.
This is the increase in supply current for each input that is at the specified TTL voltage level rather than V
CC
or GND.
Measured by the voltage drop between the A and the B terminals at the indicated current through the switch. The lowest voltage of the two (A or B)
terminals determines the ON resistance.

This parameter is warranted but not production tested. The propagation delay is based on the RC time constant of the typical ON resistance of the switch
and a load capacitance, when driven by an ideal voltage source (zero output impedance).
