Quad 1-of-2 multiplexer/demultiplexer

9.2 ON resistance

[1]

[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.

9.3 ON resistance test circuit and graphs

Table 7.

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