Static characteristics

All typical values are measured at V

amb

°
C.
[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 A and the B terminals at the indicated current through the switch. ON resistance is
determined by the lowest voltage of the two (A or B) terminals.
10. Dynamic characteristics
[1]
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).
