Quad 1-of-2 multiplexer/demultiplexer
9.2 ON resistance
[1] Typical values are measured at T
amb
=25C and nominal V
CC
.
[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 of the voltages of the two (A or B) terminals.

ON
At recommended operating conditions; voltages are referenced to GND (ground = 0 V); for test circuit see Figure 7.
